SPC Performance ZINC SHIMS 4x6.5x3.0 deg.

SPC Performance is known for making suspension parts that help you get your alignment dialed in just right. These heavy-duty truck axle shims are a quick and accurate way to adjust the front or rear axles on most popular tandem trailers and trucks. They are designed to help you correct alignment issues quickly and effectively.

These new Zinc Alloy shims offer a step up in performance compared to traditional aluminum shims. For a small increase in cost over aluminum, you get the hardness similar to their premium manganese bronze shims, along with much better compression strength. This means they hold up better under load. The shims measure 4 inches wide, 6.5 inches long, and provide a 3.0-degree angle adjustment. If you're using Z blocks or axle spacers, these shims help spread the load to prevent crushing.

This part number includes six shims in a box, giving you enough to tackle the job. They are built for over-the-road use, meaning they're made to handle the demands of daily hauling.
