I'm familiar with the road manners of a locker. I had a built 79 Bronco on 44's that was locked. So the Tru Trac is basically a beefed up LSD?

 

It's not really a beefed up LSD...it's a regular one [8D] It just uses gears instead of clutch packs. A clutch pack LSD can last just as long as a gear-to-gear if the proper maitenance is done on it.

 

im not for sure if it did rom all i know is it would go through some mud and pull the hell outta stuff lol, if this means anything, i know it was the only 4x4 i had ever seen that with it being in 2wd when i had it in the air i could spin the tires and the front transfer case driveshaft would turn and so would the other tire, but like i said i did not know much about it i got it used, and i love it, but if it is is there anyway i could just look and tell?

 

PORC has the Truetrac for the 9.25 too which will beat the heck out of Randys/West coast etc....pricing.

One thing to remember about the Trutrac though is that the torque bias is pretty low meaning it does not "lock up" 50/50. It applies a limited amount of torque to the wheel with traction vs. the one with no resistance. The Auburn Gear unit however, has almost twice the torque bias of the Trutrac and will come as close to a 50/50 torque split as you can get with a LSD.

That said, if your off roading with an Auburn or Truetrac and you lift a tire, your done. Some "technique" driving (feathering the brakes and gas) can get the LSD to transfer torque, but if you lose momentum and lift a tire, you basically have an open differential.

I think a great combo would be to have the Auburn LSD in the 9.25 and get a Eaton E-locker or ARB for the D44 front. Then you will have excellent traction improvement over stock (Or LSD trucks for that matter) and still have a good mannered daily driver. IMHO

 

I wish I had a locked rear end, I don't tow so im thinking I might invest.
