I picked up a 8.8 rear with 3.73 and a max grip differential out of a '06 Saleen today and it needs differential fluid. It also has ~32k miles on it. Any recommendations on the diff. fluid or anything else?

Btw, I have the Cobra Pinion Flange for the install already

Sounds like a good time for some suspension upgrades in the rear. Dont forget the beer either.

Yeah I've been thinking of doing LCAs while the rears off, but I'll have to see how the mod money accounts looking. A few 6 packs might be in order for afterward

It looks like I'll need about 2 quarts of Royal Purple diff. fluid and some Limited Slip additive. Is that correct?

3.75pts of SAE 80W-90 GL-5 gear lube
Track lock add 4oz. for friction modifier.

Yay/Nay?

That came straight from my hayes manual, for anything else I would swing by a dealership and see what they recommend/use.

Sounds good, thanks for the help
