What oil does Truetrac use?
A quality, petroleum-mineral based, GL5 rated 80w-90 gear oil should be used. Synthetic oils are not recommended for Truetrac applications.
Can you do a burnout with a Truetrac?
If one tire breaks traction, the amount of rotation (or spin) is controlled. The torque is then sent to the other tire that still has traction. But yes, a truetrac will do a one wheel burnout if one tire is in water and the other isnt.

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.
Is Truetrac good for drag racing?
Member. The TrueTrac is not recommended for drag racing, expecially with a stick car. The helical gear set up in a 8.8 differential does not allow sufficient gear contact surface area to withstand shock loads of repeated clutch dumps with slicks!
Who makes Truetrac?

EATON
The Detroit Truetrac from EATON is a helical-gear style differential. It operates as an open differential under normal driving conditions, so that one wheel can spin faster or slower as necessary.
Where are Eaton Truetrac made?
The TrueTrac has been made in Taiwan for probably 5 years now.
What is a Tru Trac?
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 Eaton Truetrac good?
All of the feedback that I have received from customers indicates that the unit works very well for mud and snow, while going unnoticed during every day driving. When used in situations like rocky trails where one wheel gets off the ground, the unit will not lock up 100%.

What is Truetrac posi?
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.
Are Eaton Truetrac made in Taiwan?
The TrueTrac has been made in Taiwan for probably 5 years now. Taiwan isn’t China when it comes to parts/manufacturing, there is some decent stuff that comes out of Taiwan.
Is Truetrac a limited slip?
What type of gear oil to use with truetrac?
Eaton recommends an 80w90 mineral with no friction modifiers, hard to find anything without the modifiers. Truetrac needs an amount of friction for the torque biasing to work properly. All I can find is HD Penrite gear oil but it only comes in 20L drums.
What kind of oil does a Detroit truetrac take?
Here’s what Eaton says today in the documents currently on their website: Detroit Truetrac A quality petroleum (mineral) based oil is recommended. Synthetic oils and friction modifiers should not be used, as they will decrease overall performance.
What type of diff oil do you use?
What diff oil are people using? Eaton recommends an 80w90 mineral with no friction modifiers, hard to find anything without the modifiers. Truetrac needs an amount of friction for the torque biasing to work properly. All I can find is HD Penrite gear oil but it only comes in 20L drums.
What type of fluid do you use in your truetrac?
For the TrueTrac use ONLY a GL-5 fluid that is NOT syn or FM modified. Be careful, because some dino gear oils still have FM in them. I would recommend a simple choice such as the W/M SuperTech GL-5 80w-90.
