Product Details
These SPC Performance axle shims are made from a Zinc Alloy, giving them the hardness of manganese bronze and better compression strength compared to traditional aluminum shims. They measure 2.5 inches wide by 5 inches long, with a 0.5-degree angle, and are designed for aligning the front or rear axles on most popular tandem trailers and heavy-duty trucks.
Using these shims can be a fast and accurate way to correct axle alignment. The Zinc Alloy material offers a notable step up in performance and durability for a small cost increase over aluminum. If you're using Z Blocks or axle spacers, these shims help spread the load to prevent crushing, ensuring they maintain their shape and function under stress.
Each part number ordered includes a box of six shims, providing enough for multiple applications or replacements.
