Product Details
This box contains six SPC Performance heavy-duty axle shims, each measuring 2.5 inches wide by 5 inches long with a 1.5-degree angle. These shims are designed for aligning the front or rear axles on most popular tandem trailers and trucks. They offer a fast and accurate way to get your axles dialed in.
Compared to traditional aluminum shims, these new Zinc Alloy shims bring a notable upgrade. You get the hardness similar to premium manganese bronze shims, along with much improved compression strength. This means they hold up better under load, especially if you're using Z Blocks or axle spacers, preventing the shim from crushing. The zinc alloy construction provides a solid performance advantage over aluminum.
