ALUMINUM LEAF SPRING PACK DEGREE SHIMS

Leaf Spring Shims: Correct the caster or pinion angles in your leaf spring truck, Jeep, or SUV using our heavy-duty leaf spring shims. These leaf spring shims are designed to be permanently attached to the leaf spring pack using the leaf’s cross-pin. The cross holes are counter-bored against the angled surface to ensure the cross-pin gets even clamping force across the spread of the pin’s top surface. They come in aluminum for 2.5″ wide leaf packs.
