Product Details
These SPC Performance axle shims are designed for heavy-duty trucks and tandem trailers, providing a quick and accurate way to adjust front or rear axle alignment. They are made from a Zinc Alloy, which offers better hardness and compression strength compared to traditional aluminum shims, for improved performance and durability. Each box contains six shims, ready to help you dial in your alignment.
The Zinc Alloy material used in these shims brings a notable step up in performance. It provides a hardness similar to manganese bronze shims and significantly better compression strength than aluminum. This means they can handle the demands of heavy-duty applications while resisting crushing, especially when used with Z Blocks or axle spacers. The dimensions are 3.5 inches wide, 6.25 inches long, with a 4.0-degree angle to achieve the desired alignment correction.
