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.
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.
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. Its versatility makes Detroit Truetrac the ideal traction solution for almost any type of vehicle.
Is a Detroit Truetrac a posi? – Related Questions
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.
Is limited slip better than a locker?
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 Positraction and limited slip the same thing?
Positraction, or positive-traction rear end, is a General Motors brand name for a limited-slip differential (LSD). It helps distribute power to the rear wheels and helps them spin at the same speed.
What are the three types of limited slip differentials?
The three key types of LSDs are mechanical (clutch-based) LSDs, viscous LSDs and helical/Torsen (torque sensing) LSDs.
How do I know if I have locking limited slip differential?
Is limited slip and Posi Trac the same thing?
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.
“The G80 locking axle provides a greater traction advantage than limited-slip differentials in most situations, while its automatic engagement requires no driver involvement, unlike some competitors’ electronic lockers, which require driver activation,” said Jeff Luke, executive chief engineer.
Does limited slip spin both tires?
The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. 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.
Why is a posi rear end good?
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 same as locking differential?
`LOCKING DIFFERENTIAL’ IS SAME AS POSI-TRACTION ON YOUR TRUCK.
Which is better limited slip or open differential?
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.
Why is a limited slip differential better?
Limited slip differentials compensate for a loss of traction in one wheel, offering you more control even when driving on slippery or rough roads. A limited slip differential increases a car’s power and speed by utilising engine power more efficiently, thus allowing for a smoother and more enjoyable drive.
The limited-slip differential was conceived to improve motor vehicle mobility in situations where the traction conditions are not the same for both driving wheels. More driving force is directed to the wheel having the better traction to improve the ability of the vehicle to pull out of mud or snow.
Is limited slip diff good in rain?
Limited slip differentials can be dangerous in slippery conditions like a rain soaked road.
What are the four types of differentials?
There are four common types of differentials on the market – open, locking, limited-slip and torque-vectoring.
How often do you need to change differential fluid?
On average, vehicles need new differential fluid every 40,000-60,000 miles. However, every car has different requirements, so it is important to check your owner’s manual for recommendations specific to your vehicle.
