What is TrueTrac with Power Lock

Truetrac
What kind of oil should I use? Can I use synthetic? 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.
Can I use the stock bearings?
In most cases the Truetrac units work with the factory (stock) bearings. The exceptions are: 10 bolt 8.5\8.6 GM axles, the “Performance” Dana 35 & 44 and GM12 bolt with 35 spline axles. No other “special” setup is required.
What kind of break-in is required?
The Truetrac units do not require a break in. The unit’s internals will take a little time (depending on driving conditions) to “seat.” Afterwards there will be a slight improvement in its performance.
When does the Truetrac lock up?
The Truetrac is a helical gear limited slip differential and never “locks up”. 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. The torque is then sent to the other tire that still has traction.
I use my car on the street and on the strip, will the Truetrac hold up?
On the street, the operation of the Truetrac will be transparent. You will not know it is there until you need it. In racing situations the unit will apply torque to both tires and launch straight as an arrow, time after time.
How much horsepower and torque will the Truetrac take?
There are many factors to consider when determining if a specific differential will last in your vehicle. Horsepower and torque are important factors. However, the weight of the car, tire height/width, the terrain and suspension are all important things to take into consideration.
For example, a setup that uses street tires will live longer because both tires will break loose and spin before any real strain is put on the unit. But as the tire gets wider, the stress on the unit increases because the traction is greater. When in doubt, the best bet is to call us with your specific application and driving conditions.
Can Truetrac be used in the front axles of full time 4 wheel drive jeeps and trucks?
Yes, it can. You will find will find Truetrac differentials to be very smooth yet effective in either end of your vehicle.
Can I repair the Truetrac if I need to?
The worm gears inside a Trutrac are maintenance free, and do not require regular service. Internal failure usually results in the damage of the worm gear pockets. Therefore, they are not rebuildable.
What is the warranty?
The Truetrac unit is covered for one year from date of purchase against defects in materials and workmanship up to a 38.”
FYI - We had had a lot of problems with the Truetrac holding up, these problems seemed to occur after Eaton bought out Detroit, who initially built the Truetrac. I have suspended offering the Truetrac until Eaton resolves the durability problems. I use to recommend them for up to 600 rwhp. Bob

Bob,
Thanks for the info. I saw a particular website offering Strange S60 rear end with the True Trac "with Power Lok"
Kinda threw me off, never seen that before and don't know what it means.
I also learned that if you have a True Trac and decide to change differentials then you need different axle shafts, since the splines for them are different.
What LSD would u recommend for street/strip use? My goal is 500~600 hp/tq

Bob, I am in the market for a new rear end. You said you prefer Spools. Is that good for a DD? I thought Spools were for race cars only? I am very confused about the differences between Wavetrac, Detroit Locker etc. could you please explain what would be best for my Daily Driven 1999 Z28 with 4L60E built to handle 400 rwhp? The car now has about 350 rwhp. Thank you very much! Tony

Bob, what I'm looking for is a 9" Ford rear end that is way stronger than stock ten bolt, yet performs like stock rear end. I read a post from someone that said the Detroit locker pops and make all kinds of noises. And locks and unlocks by letting off gas and stuff. I don't want any crazy **** like that! HELP!!!!!
