I thought that's the way to go... I blame my right foot and thumb...

 

they are a good combo but when you run it as much as you're saying you do....the .001" matters ya know? if you got the cash and the people that know how just upgrade to the 14bolt out of a SS or VHO imho. thats what im going to do with my CC when something breaks

 

Yeah it sucks that the only shop around here that'll do differentials and other things is garbage and does **** work. Oh well pretty soon ill learn it all and be Mr fix-it. I wouldn't mind upgrading to 14bolt you know how difficult?

 

14b is not too tough at all and there are multiple options.

this is not the first of the tru-tracs i have seen let go. another reason to stick with eaton LSD.

 

My g80 let go at 15k

 

Sorry for your luck thats never fun.

TrueTracs suck for drag racing. They break often in car applications they just cant take initial shock loads thats what does them in. The stock 8.5" is a great diff though it gets slagged on often but its really a stout unit BUT it has to have the right parts installed.

To make it bullet proof you need to upgrade to 31 or 33 spline BOLT IN axles. This can be done with either c-clip eliminators ( which I think suck ) or weld new housing ends onto the housing. You could even go for 35 spline if you want. Eaton or perhaps Mosers new wavetrac ( lifetime guarantee not to break ) and a solid pinion spacer and you could pull wheelies with your trucks before it let go.

Not saying this is "cheap" but the 8.5" stocker is worth upgrading it can take the abuse its just how its set up in factory form thats crapola

 

Am I missing something here? How are there pieces of spider gears if he has the truetrac???

 

Preston129. I was thinking the same thing.
Did you pay for a t-trac?

 

I am in the process of dealing with this right now... I broke my first g80 went and paid for a tru trac and 4:11s now realizing I got 4:11s and some used g80... I got took... invoice even says tru trac and Yukon 4:11s I guess that's what happens when you don't pay attention and trust people...

 

Shitty.
