MA BZ SHIMS 4x6.5x0.5 (6)

Heavy Duty Manganese Bronze Truck Axle Shims. Width - 4.0" | Degree - 0.5° | Length - 6.5". These shims offer top-of-the-line compression strength and hardness to maintain alignment settings. Note: Ordering one Part Number supplies six shims in a box. When placing an order, spring pad length and width are needed. If using "Z Blocks" or other axle spacers, a load spreader (like SPC's Axle Spacer Plate) is recommended to prevent crushing. Specialty Products offers Truck Axle Caster Shims in three different alloys (Zinc Alloy #10703, Manganese Bronze #10704, Aluminum Alloy #10705) to match price point and mechanical requirements.
