My truck has a 4 in body lift on it. The rubber and what not used to lift it is squishing and cracking and looking like crud. What would you guys on a budget use to fix this problem on a budget? I have heard hocky pucks, wood, steel pvc pipe from home depot etc... any openions would be appreciated. One other question.... what kind of lift is needed for rock crawling meanies that have all that travle in their suspention? You know, the guys pulling up on the ramp with one tire 4 feet up the ramp and tire in the wheel well and all three other tires on the ground?
