ok so yesterday i finally got my gears installed and my underdrive pullies and the car is amzing now. i also tuned it with the diablosport predator tuner as well so it seems like a new beast. dez-racing rules they charged me 245 bucks for the install of the gears the rear end rebuild kit and the pullies. i figure most places charge alot more than that just for the gear install.

but my question is should i go change out my rear end fluids or what not, like what fluids should i use as well? thanks.

 

Well if you just had your gears installed they just replaced all your fluid too. So you do not have to worry about it, unless you want to spend the money and have Royal Purple fluid put in it. IMO I would not do it, but I would have had them use RP when they replaced my gears.

 

U should Royal Purple EVERYTHING (oil, tranmission oil (ATF), power steering fluid and rear diff. oil) its good stuff and thats what i use!!

 

Royal Purple, Amsoil, Redline....all good stuff. Don't need friction modifiers added to the rearend fluid if you use one of these synthetics. Lasts virtually forever.
