Product Details
SPC Performance is known for making specialized alignment parts, and these axle shims are a great example of that focus. If you're working on a heavy-duty truck or tandem trailer and need to dial in your front or rear axle alignment, these shims are a fast and accurate way to get it done. They're designed to fit popular tandem trailer and truck axles, making them a versatile option for many applications.
What sets these apart is the Zinc Alloy material. Compared to traditional aluminum shims, this Zinc Alloy offers improved hardness and much better compression strength. This means they're less likely to crush under load, especially if you're using Z Blocks or axle spacers. The shims measure 5 inches long, 2.5 inches wide, and provide a 2.5-degree angle adjustment. You get six shims in a box, which is usually enough for a single axle adjustment.
