Finally, there's the backyard engineering way of permanently converting an open differential into a spool by welding the spider gears together which is commonly called a "Lincoln locker" (named after the welder brand). An aggressively set limited slip differential will force the two tires to spin together while a lightly tuned limited slip will only transfer minimal power. OX Off Road, LLC has developed a manually engaging locker called the OX Locker that locks and unlocks using a cab mounted shift lever that is connected to the differential by a shifter cable. In the event that one wheel loses all traction, power will still be transmitted through the clutches to the other tire up to the threshold of the friction plates. While it may be tough to visualize, in a Torsen differential, power is applied to spur gears attached to the differential carrier that then rotate a worm gear on each axle shaft. Any movement beyond that encountered during normal driving conditions forces the differential to "lock up" and send power to both wheels while still maintaining a 1:1 differential ratio. Toresn style differentials including the Eaton TrueTrac work on the simple principal of worm gears in that a worm gear can turn a spur gear but a spur gear cannot turn a worm gear. Anyone put a torsen style differential into their 2nd gen? At the differential, the shifter cable moves a shift fork that slides an internal engagement collar over one of the side gears to lock its movement to the carrier. the worm wheel will not turn a worm gear). Lockers are for Drag Racers. The lack of a differential mechanism is also why a spool should never be used on a street driven vehicle. Eaton posi perf. I recently learned about them and want to give them a try. Getting ready to modify the rear end in my MT-82 '13 GT. Torsen toque biasing differentials use cross-axis helical gears that limit the difference in speed between the two axles. Check out this and other Eaton Truetrac Differentials at http://www.summitracing.com/redirect?banner=SocialYT515. Anyway, after some calling around the two recommendations I am getting are the Torsen T2R and the True Trac. To find the street legal laws for your state including maximum suspension lift heights and tire size rules visit LiftLaws.com, Copyright © 2019 Crawlpedia All Rights Reserved | Privacy Policy | Contact Us, Russian Translation by Russian Dodge Ram Club. Electric and air shifters are available for the OX Locker, however, we feel that those options take away from the simplicity, reliability, and positive mechanical feedback of the design. Tell me how it does with real tight turns. 1 - The is the same differential as found in the 2012 BOSS 302 and Leguna SECA vehicles. Help me decide on either an Eaton posi or Detroit Truetrac differential June 14, 2011, 11:47 AM. The locking system is overly complicated in that it requires an electric switch to open an electric solenoid and run an air compressor to provide air to the differential and mechanically lock the spider gears. (This procedure is called brake-throttle-modulation and is taught by the US military to all Humvee drivers.). Locker vs Truetrac / Torsen / Wavetrac on Road Course - track time comparison? I am going to try a true trac..I just broke my rearend again for the 2nd time lastnight,first pass out this year.I broke axle and cracked torsen last pass last year and installed strange axles and FFRP cobra diff.I havent got it torn down yet but feels like spiders let go! When the vehicle turns, the axle shafts will rotate at different speeds (effectively turning opposite to each other) which causes the worm gears on the shafts to rotate the spur gears on the carrier. Its versatility makes Detroit Truetrac the ideal traction solution for … The principle is that you can drive a worm wheel with a worm gear, but because of the angle of attack between the gears you cannot back-drive a worm gear (i.e. A differential with this type of locking mechanism is called a differential locker or simply just a "locker". Detroit Lockers, sometimes called a gearless differentials, have been around since the early 1940s and have proven themselves to be extremely reliable and effective in everything from rock crawling to drag racing. While the advantage of the original response of Torsen is enjoyed, this multi-purpose model supports various applications with wide adaptability ranging from the front differential to the rear differential. If this is your first visit, be sure to check out the FAQ by clicking the link above. The shifter has a spring loaded positive engagement collar and has a knob that can also be rotated in to lock it in place. Eating a steady diet of government cheese, and liv, http://www.tractech.com/docs/DetroitTruetrac04.pdf, (You must log in or sign up to reply here. That said, the design does have its share of issues. You may have to register before you can post: click the register link above to proceed. Detroit locker style lunchbox lockers are offered by various manufacturers and are very popular because they are affordable, effective, and do not require removing the differential from the vehicle to install them. [ Video: Inside a Limited Slip Differential ]. When I am accelerating out of a corner the differential free spins for 90*-180* before locking up. I am wondering what the pro's and cons of the Torsen differential vs standard are? Additionally, because the unit requires quite a bit of differentiating force to disengage, driving in low traction conditions like rain or snow can be a bit unnerving because the Detroit Locker tends to stick or open unexpectedly. The Zexel is a gear drive like the Tru-trac. Just like in a manual transmission, the clutches will wear out over time and become less and less effective until they eventually provide no benefit. Unfortunately though, the design has a few quirks that don't make it a great choice for street driven vehicles. Need your feedback - pros & cons I am in the process of ordering a Moser 12 bolt for a 95 Firebird. A properly set up suspension will not spin the inside tire. Starting the front axle ring and pinion this weekend. They will switch L2R and R2L on slick roads under load[trying to find grip] , but @ Drags they've all gone straight. While most limited slip differentials can be rebuilt, it's tough to justify the cost knowing that it will wear out again and again, whereas a Torsen differential does the job better and the all gear design will never need servicing. Immediate torque distribution suitable for the terrain not available with open differentials is possible. I am in the process of regearing to 4.88's. Can anyone tell me if the two brands behave the same? Spools are used exclusively for desert racing, hill climbing, mud racing and other off-road applications where a differential is not needed and reliability and strength are critical. If this Torsen diff has a TBR of 2:1, the tire with more grip would only be able to provide twice the amount of torque that is provided to the tire with less grip. The T2 used in the Boss has a torque bias ratio (TBR) of 2.5, so the wheel with traction can get up to 2.5 times the torque than the wheel with less traction. Finally, every time the vehicle turns and the teeth on the side gears override each other, the unit makes a loud clicking or crunching noise that makes it annoying in and around town. You can only purchase this unit from a Ford Dealership or the Ford Racing Parts website. Maintenance-free, it features smooth, automatic operation in forward and reverse. To prevent power from going to a wheel with little or no traction, a locking mechanism is needed to shift that power over to the tire with more traction so that the vehicle can continue moving forward. From our friends at Eaton - we take a … For something cheaper and easier to install, mini spools replace just the internal spider gears similar to a "lunchbox" style Detroit Locker. When a large differentiating force is applied to the gears it forces one of the side gears to ride up and over the teeth on the carrier gear which disconnects that axle from the differential for a split moment. Torsen differentials are direction specific so reverse rotation units are required for front axle and reverse rotation applications. The key to a well performing limited slip differential is selecting the proper friction plates, spring load, gear oil, and friction modifiers for the given application. It generally provides better traction to both wheels than most clutch-type limited slips. I've had several in different vehicles as much safer on slippery stuff [than clutch or locker]. Here at JTEKTTorsen ® North America, we strive to design, manufacture and supply first rate helical gear limited slip differentials. Locking differentials come in various forms and functions ranging from a mild limited slip found in many OEM applications all the way to a race-only spool that permanently locks the wheels together and has no differentiating function. Torsen ®: Geared for the Road Ahead. A spool locks both axle shafts together permanently so that they will always turn together. A differential spool is, in fact, not a differential at all. Detroit Truetrac is designed to handle more torque (power) than the axle shafts it drives. Auburn Gear makes and electric locker called the Ected Max-Locker that is both a clutch style limited slip and an electric locker, however, we don't recommend this unit for the same reasons we don't recommend limited slip differentials. The biggest problem with limited slip differentials is that every time the vehicle turns and the tires are forced to spin at different speeds, the clutches are rubbing against each other and causing wear. The most common type of spool is a Full Spool that replaces the entire differential carrier. Modern automotive differentials are available in many different styles ranging from standard open differentials, to limited slip models, to selectable and automatic lockers, and fixed spools that have no differential function at all. Horsepower has little influence on the differential since it is more of a function of engine RPM. The locker is extremely simple and comprised of only 3 ratchet gears (one attached to the carrier and one on each axle shaft) that are pressed together by a pair of heavy springs. I saw on an americanmuscle video recently that the guy selected a non performance pack for a few reasons , one being brakes getting in the way of his plans (im assuming lightweight drag wheels) and also said the torsen differential would just get in the way. Detroit lockers are fixed in the locked position until a high enough differentiating force causes them to unlock temporarily. The T2R has a 3.5 bias and the new design Tru-Trac has a just under 3.0 bias. This means that you need to lift off of the throttle to let the unit disengage. Electric lockers, or E-Lockers as they are more commonly called, use an electric current to engage the locking mechanism in the carrier to convert from an open differential to a spool. Displaying 1 - 3 of 3 results Sort: Product Image Product(s) Part # Torsen T-2R torque-bias differential, High Bias, Ford 8.8” differential. While it may be tough to visualize, in a Torsen differential, power is applied to spur gears attached to the differential carrier that then rotate a worm gear on each axle shaft. Unlike most locking differentials that are open and use a locking system to lock the axles together, the Detroit locker rests in the locked position and only unlocks temporarily when a large enough differentiating force is applied to it. 4.56 w/ 35s S.B., Aug 16, 2017 #3. When the current is turned off, springs push the ball bearings back into their resting position and the locker turns back into an open differential. or truetrac which is better. This turns the locker into a spool until the Drive Away Lock bolt is removed. Truetrac® differentials are unique in that they increase traction but do not affect steering or wear out prematurely; these problems are common with limited-slip differentials that use clutch plates and springs. However, when accelerating (torque applied), the six helical-gears inside the unit smoothly and quietly engage, applying torque to both rear wheels equally, maximizing traction (think two equal length black … Eaton Truetrac The Eaton ( eaton.com ) Truetrac is a gear-driven limited-slip differential. TrueTrac performs like a conventional (open) differential, until there is a loss of traction. Open vs Limited-Slip Differentials. Both operate under the same design with minimal play. First, the gap between the teeth on the gears allow some slack in the movement so every time you apply or let off the throttle it will lag and jerk a bit. This new design lets both gears to turn each other similar to an open differential, however, the angle of the teeth on the gears has been set specifically so that the sliding friction between them acts as the locking mechanism. As a vehicle turns, the outside wheel turns faster than the inside wheel because it covers more distance. Ultimately though, when an air locker works, and is installed correctly, it works very well. At the differential, the airline feeds a collar that sits up against the bearings and has 2 O-rings between which the air flows through a small hole in the bearing journal. A differential allows power to be applied to both wheels while allowing them to rotate at different speeds. It has steel wear pucks that are used to increase the bias ratio but if you unload a T2R sufficiently it will behave exactly like an open differential just like the T2 does. ARB Air Locker are the most popular selectable lockers on the market today because they have been around since the late 1970s and offer lockers for far more applications than any other locking differential. No problems here with the true trac in my IRS car.... :shrug: Have you tried a AutoX with it? You are exactly right about the bias ratio though. Once the internal spider gears are locked, the differential becomes a spool and both tires will turn together. The Detroit Truetrac is going to be an excellent all-around differential that can handle the power you supply with your street car, and still manage to give you great driveability. I sell quite a bit of the Eaton/Detroit TrueTrac worm gear drive differentials for performance street use. Compressed air from an air compressor, air tank, or CO2 tank flows through an airline to an electric solenoid valve that opens to allow air flow to the air locker at the flip of a switch. Installed an ARB locker and chromoly shafts in the rear. In more specific terms, an electric current energizes an electromagnet that puts pressure on a series of ball bearing cams that use the rotational force of the differential to lock one of the side gears to the differential carrier. Current versions of the Torsen, like the TrueTrac, have moved away from spur and worm gears in favor of worm wheels that allow for smoother operation. Does the Eaton Truetrac have the same torque proportioning effect as the Torsen or does it either freewheel or lock like a clutchpack? – KMP Drivetrain Solutions ... Eaton TrueTrac is similar design to Torsen. Find Eaton Detroit Truetrac Differentials and get Free Shipping on Orders Over $99 at Summit Racing! Torsen style differentials available today do not require any friction modifiers or additives since their internal gears are engineered for use with conventional gear oil. Locks up quick and hard, lots of sideways motion! I had one in my Miata. The Torsen T2R does not have any clutch packs in it to add pre-load. Detroit Truetrac – Smooth Maintenance-Free Traction The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Another cool feature of the Ox Locker is that in the event of a cable failure, a Drive Away Lock (sold separately) can be inserted into the diff cover to lock the differential into the locked position. ). The drivetrain is absorbing that engagement and 3rd is the weak point. ... Let’s say we have a two wheel drive vehicle that is equipped with a Torsen differential. The following lockers are also based on the same principal of the Detroit Locker: ARB Air Locker and Yukon Zip Lockers use compressed air to convert from an open differential to a fully locked spool. Selectable lockers use air, an electric current, or a shifter cable to switch between an open and locked differential. Discussion in 'Cobra R's' started by tomshep, Feb 6, 2006. E-lockers are the easiest type of selectable locker to install because only one small wire needs to be run from a switch on the dash to the differential. Spools are a one piece fixed design that sends power two both wheels at all times with no differentiating function. The Detroit Truetrac is a Torsen style differential that provides constant power to both drive wheels at all times while still allowing for wheel speed differentiation. They were used in the Glory days of Trans Am racing, but they had no alternative then. About Torsen ®. Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at slightly different speeds for smooth cornering. From the military AM General HMMWV to Audi Quattro sedans and SUVs, Torsen differentials provide the traction and handling that you need. The Torsen differentials fit Mustang 8.8" rear-ends, both solid axle and IRS, and are available in 28 spline and 31 spline versions. The majority use Tru-track or Torsen, the new Mustang GT-350R comes with a Torsen. Due to its design, the Detroit locker is ideal for trail running, rock crawling, off-road racing, drag racing, and heavy commercial equipment. Aug 16, 2017 at 1:49 PM #4 #4. Once the air pressure is released, internal springs will push the engagement collar back to its resting position and the locker becomes and open differential again. The Eaton Truetrac is available for the rear axle of 1500s and LOOKS similar to the Torsen design but it works on a somewhat different principle. When the shifter is moved back to the open position, the collar is moved back to allow the differential gears to move freely again. Installing a spool in a front axle will cause significant internal binding during turns and will put undue stress and strain on the axle shafts and u-joints. There are also many things that can easy fail or go wrong ranging from leaking air lines to damaged O-rings to failed electrical connections, or even a blown fuse. One flaw to the ball bearing cam design is that it tends to stick in the locked position even after the locker has been turned off as long as torque is still being applied to the differential. The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Detroit Locker differentials are not recommended for steering axles unless the hubs can be disengaged for use on high traction surfaces. In zero traction situations where a tire is up in the air, the Torsen differential will not be able to transfer power to the tire on the ground by itself due to a lack of differentiating force. Limited slip differentials use spring loaded clutch-style friction plates to help keep the tires moving at the same speed. Maintenance-free, it features smooth, automatic operation in forward and reverse. Welcome to Torsen ®.Since 1984, we’ve provided class-leading helical gear, torque-sensing differentials to premiere auto manufacturers. ALERT: On backorder. The spur gears are connected with another set of side gears that lock them together in a 1:1 ratio that limits the difference in speed between the two tires. While there have been many unique differential designs that have come and gone over the years, the most popular locking differentials used today are the following: Limited slip differentials, also known as Posi or Trac-Lock differentials, use clutches and springs to increase the friction of the differential gears to prevent them from turning at different speeds. A standard "open" differential works perfectly when both tires are on a high traction surface, however, if one tire loses grip (on ice or if it lifts up in the air) then all of the power applied to the axle will take the path of least resistance and spin that free tire only. Once a limited slip has worn out, we highly recommend installing a Torsen or Eaton TrueTrac differential. The design works so well that the US military chose the Torsen differential as standard equipment on the Hummer. This differential comparison article is ©Copyright Crawlpedia.com - Do not repost or reprint without written permission. In contrast, a T2-R has a TBR of 4. Torsen vs. plated limited slip differential. A quick solution to this problem is to apply the brake slightly to provide resistance to the free wheel and then apply the gas to lock the Torsen mechanism. Along the same lines, when the unit is engaged, shifting from forward to reverse (or vice versa) requires the cams to unwind and rotate backwards to re-engage in the opposite direction which can feel a bit sloppy or clunky at times. For a more in-depth understanding, make sure to watch this classic video of how a differential works. Instead, for front axles paired with spooled rear axles, we recommend running a Detroit Locker or a Selectable Locker. Because this ratio is locked, even if one tire is spinning on ice, the other tire will be forced to turn and move the vehicle forward. Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. I have the eaton truetrac, works bitchin! Detroit lockers are available as complete carrier differentials as well as smaller units nicknamed "lunchbox lockers" that replace just the spider gears in an open differential carrier. The Truetrac will provide a near lock state when the power is applied, but it performs as an open differential until traction is needed. Inside the locker, compressed air pushes an engagement collar over one of the differential side gears to lock it to the carrier. Crawlpedia is proudly supported by Filthy Motorsports, a specialty off-road racing and 4x4 parts shop in Boulder, Colorado. It's easy, affordable and very effective, just contact us to get started! Want to see your banners and links on Crawlpedia? Detroit Truetrac Lockers are maintenance free, fully mechanical, Torsen style limited slip differentials with helical gears instead of clutch packs (which wear out over time) to provide constant torque to both wheels while still allowing for smooth turns on pavement. Toresn style differentials including the Eaton TrueTrac work on the simple principal of worm gears in that a worm gear can turn a spur gear but a spur gear cannot turn a worm gear. The OX Locker does require routing a shifter cable from the differential to the shifter so some measuring is required when ordering the components and the path of the cable should be smooth with large arcs and kept away from moving parts and high heat. In this article we will go over the most popular aftermarket differentials available today, in detail, so you can choose the right one for your application. The budget does not allow an ARB and stronger shafts for Dana 30. The Eaton E-Locker is the only aftermarket electric locker available today. Torsen Differentials. Using synthetic blend or full synthetic gear oil will not harm the differential, although, it will slightly reduce the torque bias ratio. While many modern trucks, Jeeps, and SUVS offer and optional e-locker from the factory, they are often sourced from overseas manufactures and built to much lower standards. I had a Zexel-Torsen series 2 that lasted less than 500 miles as a daily with little track time. The HUGE advantage of the Torsen Differential (Torsen stands for Torque Sensing) is that it puts the power to the tire with the most traction. Other than a few rare exceptions, spools should only ever be installed in rear, non-steering axles. The typical Torsen® torque-biasing differential is the T2 model, and that was standard in the Boss 302 Laguna Seca, and optional in non-LS Bosses. To engage the locker, you simply move the shift lever into the locked position and to disengage the locker you move it back to the open position.
