I recently purchased a '90 Jimmy for my son. We have started doing minor repairs and upgrades. Our next project is a lift and tires and wheels. We are planning on a ProComp 4" lift and are in a small dispute about whether to put on 33" or 35" MT. The Jimmy is fully loaded 350, 3.73 gear ratio, quad shocks, trans-oil cooler. I prefer the 33's because of gear ratio and wear and tear on the transmission. My son's reason for the 35's is "attitude," they just look alot better, and who cares how it drives. Any thoughts from those of you who have been there and done that?
