Default Diff upgrades?

Well i had to remove the diff from the car because i snapped a CV stub off well because I have the diff out is there any upgrades I can/should do to it before it goes back in?


I'm going to order gforce axles tomorrow but I was also thinking of a TCperformance Diff girdle



Its a 2006 with close to 490 RWHP

Check out driveshaft shops axles as well. Other then that i think the rest are gimmicks that have yet to prove they are worth anything.

It's a good time to put in a poly front diff mount either UUC or Creative Steel.

No such beast, but you could get the gears cryo treated, waste of money or not, i'm not sure.

Waste of money for sure. Its the thin aluminum case that is the weakpoint of the diff, not the gears.

Had they beefed up the area around the front mount a little more the differential probably wouldn't be such a weak point.

Ive snapped a grade 10 diff cradle bolt and a CV stub (both drivers side) so i think its safe to say that its not my case that is the real problem. I was just looking for anything that I could do as long as I had the diff out.

Ive already painted the case now i'm just waiting on my axles
