SPC Performance ZINC SHIMS 2.5x5x1.0 deg.

These heavy-duty axle shims from SPC Performance are made from a Zinc Alloy, offering a notable step up in performance compared to traditional aluminum shims. The alloy provides a hardness similar to manganese bronze and significantly better compression strength than aluminum, making them a solid choice for aligning the front or rear axles on popular tandem trailers and trucks. Each box contains six shims, each measuring 2.5 inches wide by 5 inches long with a 1.0-degree angle, providing a fast and accurate way to adjust your axle alignment.

When installing these shims, especially if you're using Z Blocks or axle spacers, it's important to spread the load evenly to prevent the shim from crushing. This attention to detail ensures the improved compression strength of the zinc alloy can do its job effectively, helping you achieve precise alignment for your heavy-duty vehicle.
