About this part

Product Details

When you need to dial in the alignment on a tandem trailer or heavy-duty truck, these axle shims from SPC Performance are a solid option. They're designed to quickly and accurately adjust the front or rear axles, helping you get everything tracking straight.

These aren't your typical aluminum shims. Made from a Zinc Alloy, they offer a notable step up in hardness, similar to premium manganese bronze, and have much better compression strength than aluminum. This means they hold their shape under load, ensuring your alignment settings stay put. They measure 3.5 inches wide by 6.25 inches long, with a 3.5-degree angle to make those adjustments.

You get six shims in a box, which is usually enough for most tandem axle setups. If you're using Z Blocks or axle spacers, these shims help spread the load to prevent crushing, adding to their durability.
