Hey guys I found a guy selling me a Grand Nation 8.5 rearend. It is all stock and nothing has been changed. My question is what do I need to do to make it hold lets say 550HP? I know I will need a c clip eliminator, but other then that I am not sure.

thanks

Probably an aftermarket posi unit.

Slippery tires.

:dontknow: LIGHTER FOOT ~ Maybe? :beer:

HAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHA nice jokes guys, but seriously what do I need to do?

Like Tom said, after market, beefed Posi Unit, and I'd up grade the Axel's and Wheel Studs.

It's a GOOD HOUSING to work with, for sure.:neutral2:

Yeah thanks all :)
