does the tru trac provide any more power to the non slipping wheel than a regular clutch pack lsd or is its claim to fame just that it has gears and doesnt wear out as fast as the clutch packs? I need some serious traction, about as close to 4wd capablities as i can with my 2wd. Its a long story as to why i have the 2wd in this situation but i cannot get out of it so im stuck. I am also trying to not spend the money on a selectable locker like the eaton E-locker. It is my daily driver though so i dont want something like a detroit locker that will chew up my tires.

 

I believe that one of the claims to fame of the truetrac is its no maintenance design like you mentioned and the other is its torque sensing design which allows it in many cases to transfer more torque to the stable wheel before actual wheel slipping occurs. It is almost the same design as the torsen differential that was used (and i think still is) in military humvees. ( http://auto.howstuffworks.com/differential6.htm ). I have had one for about a month and love it. If you are in the market for an LSD and have tires under 37" I would hands down go with a truetrac or a Torsen T-2

so what size rear end is in my truck. Mine is a 2wd 4.2L v6. Is it the 8.8" 31 spline?

Anyone else have any opinions? Will the true trac do the job or will i be better off with a selectable locker?
I need somehting becuase i have to get up a very very steep gravel driveway in ohio winters.

 

I believe you have an 8.8 look on the metal tag on the outside of your differential

 

 

Trutrac All The Way!! They do work WAY better than any clutch-based LSD, and they do, in fact, apply far, far more power to the non-slipping wheel. Unlike a clutch-based unit, they actually limit the slip of the slipping wheel.

i installed a truetrac myself. previously was a open diff. i like the performance that it offers. like one of the previous responses said, it looks just like the t-2 torsen. i had one of those in my Level II ranger, and it worked pretty good off road.
with the truetrac, clutch packs arent in there, and there is no need for friction additives when you change the dif fluid.
I belive for what you want and need, a truetrac will do just fine.
look on ebay for one. i think i paid about 400 for a new one from randys ring and pinion.

 

thanks for the info. How much does the installation cost?

 

I had a local trans shop quote me $500 installed the last time I was in there... That's using the stock gearing, of course...

If you are a good do it yourselfer ( self proclaimed ase certified!) you can do this yourself pretty easy if you have all the tools and a place to work on it at.
i changed out the front and rear gears on my 2002 f-150 under a car port and they are still runnin fine after about 9000 miles now!!
Sorry to say I dont know the price of an install. I got a couple of quotes from shops for the diff change, they said about 400-600 per axle!!!
thats when i said the hell with that, ill do it my damn self.......

 

I wish i could do it myself but i know ill screw it up. I can handle most stuff but something that requires tolerances and stuff will just get messed up.

 

2002 wonderboy, where are you located?

 

JOSIA:
located in northern cuba, i.e. florida!!!

 

how much more would a selectable locker give me? A true trac is like $500 and a selectable auburn locker is $589. The auburn is also a lsd when it is not locked.
