I'm with Snow on this. Don't worry about the SAS, you can do that in the future if you think it's warranted.

A 2" body lift and the ball joint spacers, Chevy rear springs, sliders, bumpers, and a rear locker. Boom, done. If you go 33's you might want to re-gear, but that's a good chunk of your budget.

The Downey stuff seems to be high speed suspension. You'll find opinions of Downey differ here, pro and con.

As far as the other IFS lifts go, just realize they will only raise you, you will need to tweak them and mod them to get signifigant performance enhancement....

Sounds like a E.D. add.... <img src="/forums/images/graemlins/smile.gif" alt="" />
