MA BZ SHIMS 3 x 6 x 3IN (6)

These shims are the standard for heavy-duty truck axle alignment. Made from manganese bronze for top-of-the-line compression strength and hardness, ensuring that once your alignment is set, it won't change. This kit includes six shims. Note: When ordering, spring pad length and width are needed. If using "Z Blocks" or other axle spacers, you need to spread the load to prevent the shim from crushing. Specialty Products offers Axle Spacer Plates (3" Wide - #10598 | 3.5" Wide - #10698 | 4" Wide - #10798) to solve this common problem. Specialty Products also carries Truck Axle Caster Shims in zinc alloy (#10553) and aluminum alloy (#10552) to match various price points and mechanical requirements.
