Just bought a 90 wrangler. I will be replacing the 4.2 L with the EFI 4.0 L. Putting in a T-18 and an Atlas 4.3:1. Already have those out of my old cherokee. Also putting on the Dana 44 and the 30 from the cherokee. I am wondering what some opinions are concering lifts. I am already putting on a 1in body lift to get it off of the previous owners 31's on no lift. As far as springs what's on people's minds? I am on a bit of a budget as most of the money is already gone.
