For the 2wd, its for Tahoe, Suburbans, Avalanches, and Trucks as long as they have torsion bars.

 

Pretty sure the keys are the same for either.

 

im almost postitive you can use the ford keys on a 2 wheel drive still

 

Im pretty sure I dont have torsion bars, although there are 2 bars that run diagnolly towards the motor. Im not sure if these are them but they are only held on by bolts. Can someone send a picture of their torsion bars?

 

On an '02 2wd you probably don't have them. There are a couple of braces that are about 2' long under there. Torsion bars are pretty thick and about 4' long. If you see coils, you don't have torsion bars. The cheapest and easiest way to level your truck is with 2" shackles for the rear.
