SPC Performance ZINC SHIMS 2.5x5x3.0 deg.

SPC Performance is known for making parts that help you dial in your suspension alignment. These heavy-duty axle shims are a fast and accurate way to adjust the front or rear axles on most popular tandem trailers and trucks. They are designed to correct alignment issues by providing a specific degree of angle to the axle.

These new Zinc Alloy shims offer improved performance compared to traditional aluminum shims. For a small cost increase, you get the hardness similar to manganese bronze shims and much better compression strength than aluminum. This means they hold their shape better under load, ensuring your alignment stays true. The shims measure 2.5 inches wide, 5 inches long, and provide a 3.0-degree angle. They are also designed to spread the load if you're using Z Blocks or axle spacers, preventing the shim from crushing.

When you order this part number, you get a box of six shims. These are intended for heavy-duty truck and trailer applications where precise axle alignment is crucial for tire wear and handling.
