If i was purchasing gears what all do i need to install them....Im not installing them im taking it somewhere but they said that i have to have this and that and i wasnt sure what they were talking about. If i bought the gears does that come with everything i need? im guessing like the shims and he said something about differential....can anyone help me

 

gears, an installation/bearing kit, gear oil, friction modifier, and something to calibrate the speedo if your changing gear ratios (speedcal or hand held tuner). bought all my stuff at american muscle.

 

you can actually get all this stuff at NAPA or maybe even checkers/autozone but they might not have the speed cal
