Detroit Truetrac – Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. 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.
How does a Detroit Truetrac work?
The Truetrac is a helical gear limited slip differential, not a “locker”. The Truetrac operates by transferring power from the spinning wheel to the wheel with the most traction. If one tire breaks traction, the amount of rotation (or spin) is controlled by transferring the lost traction to the higher traction wheel.
How strong is the Eaton Truetrac?
The Truetrac designs have been produced within a maximum continuous torque range from 2,500 Lb-Ft to 25,000 Lb-Ft. Increased capacity can be accomplished by larger gears and more pinion sets.
Does a Detroit Truetrac work in reverse?
The Detroit Truetrac is a helical-gear style, limited-slip differential that maximizes wheel traction and enhances driving characteristics. Maintenance-free, it features smooth, automatic operation in forward and reverse.
Is a Detroit Truetrac a posi? – Related Questions
How much is a Truetrac diff?

Proven design, low cost and effective performance all make Eaton Truetrac differentials the ideal choice for a wide variety of vehicle applications both on and off road. No maintenance – Just Traction.
Do Detroit lockers make noise?
When I step on and off the gas pedal, I hear the unit make a “clunking” noise. Why? This happens because Eaton Detroit Lockers have “backlash” or “slack” between the drive and driven teeth and you will hear this in everyday use going through corners and when transitioning from drive to coast.
Does a Detroit locker work in reverse?
It works in forward and reverse, and features unmatched strength, 100 percent automatic locking, and maintenance-free parts.
Can a differential be run in reverse?
You can flip the axle over all you want and you will change the driving direction from backwards to forwards, with the pinion and ring gear always meshing on the driving face of the gears..
How does a Harrop Truetrac work?
Truetrac gears have spiral teeth, and the pinions are mounted in pockets in the case. If one wheel begins to lose traction, the pinions separate slightly from the side gear, and wedge in the pockets. As input torque increases, the separating force increases, thus slowing or stopping the spinout.
Who makes Truetrac differentials?
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque.
Does Truetrac need additive?
Do I need friction additive/modifier? A quality petroleum/mineral based oil works best in the Truetrac units. We do not recommend synthetic oil. Friction additive/modifier is not required.
Which differential locker is best?
For vehicles with open differentials, a rear locker is by far the more popular choice, as it’s more suitable to a diverse range of off-roading situations. “If the vehicle only has open differentials we typically recommend a rear, which will be more effective when off-road hill climbing,” said Sebastian Civitarese.
What is a helical limited-slip differential?
The limited-slip differential enhances performance driving for a more exhilarating experience. The Feature: Generally found only on high-powered vehicles, the limited-slip differential minimizes front-wheel slippage, improves steering precision and allows the driver to accelerate out of a corner sooner.
Is it better to have a limited slip or locking differential?
Limited slip differentials are suitable for most driving conditions. This differential’s purpose is to make sure you have the ability to drive under normal conditions without any mishaps. However, selectable lockers make conquering extreme driving conditions possible!
Is a rear locking diff or limited slip better?
Lockers produce 100% lock-up where all the power is directed to both tires all the time when the unit is engaged. Lockers are tougher. Limited slips direct torque to both tires and when slippage occurs the unit directs torque to the tire with the best traction. LSDs do not generate 100% lock-up.
Is limited slip the same as posi?
Limited Slip Differentials (LSD) significantly increase the traction and performance of Jeeps, trucks, 4×4s, and RWD vehicles on the street, at the strip, or on the trail. Positraction is what General Motors called its limited slip differential, the term has come to refer to LSDs in general.
Is limited slip better for towing?
The Electronic Limited Slip Differential enhances vehicle stability during trailer tow operation. During high demand trailering events (such as steep grades, high speeds or with a spare tire), the system may provide a warning in the instrument cluster and reduce function or enter a temporarily disabled state.
What is better limited slip or open?
If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD. When working properly, an open differential is the best riding, most comfortable option for everyday driving.
What are the benefits of a posi rear end?
A Posi rear end will help keep your wheels on the ground and spinning at the same rate no matter what kind of road you are on. This translates into a better driving experience as well as better cornering at high speeds or on windy roads.
Is Positraction better?
When one of the wheels slips or slides, a positraction differential redirects more power to the wheel with a solid grip on the surface. It allows you to gain more traction control over the car and significantly improve its grip on the road.
