SPC Performance Steel Shim 4X6.5X1 - Pack of 6

In this box, you get six high-strength steel alloy shims from SPC Performance. These shims are designed to help you adjust caster and pinion angles, which is crucial for getting your steering and drive axles aligned just right, especially on heavy-duty vehicles. They are made for 4-inch wide leaf springs and offer a 1.0-degree change, helping to fine-tune your alignment for demanding applications like cement and garbage trucks.

Crafted from a strong steel alloy, these shims are built to handle significant compression. Their 6.5-inch pad length and 4-inch spring width compatibility mean they fit a specific range of heavy-duty leaf spring setups. If you're working with vehicles that see a lot of hard use, these shims provide a solid way to make those critical alignment adjustments and ensure your axles are set up correctly.
