Black Diamond 3" Suspension Lift Kit for 41-65 MB, M-38, CJ-2A, CJ-3A & CJ-3B

Two design elements are specifically incorporated to reduce spring stress. First, the tension side of each leaf plate is shot-peened. Secondly, the springs feature a relatively flat seat (where the spring mates to the axle), so the spring pack is not "fighting" the clamping force generated by the U-bolts. Reducing stress extends life. 1941 to 1965 models use press-fit, steel encased rubber spring eye bushings; they work best on these applications. Polyurethane spring eye bushings are used on all other models. New U-bolts with self-locking hardware are provided.
