SPC Performance JEEP CAST SHIM 1/32in. (6)

If you're working on the front suspension of your early model Jeep Cherokee, Comanche, Grand Cherokee, or Wagoneer, these caster shims from SPC Performance are a handy tool. They're designed to make small, positive caster adjustments by fitting between the lower control arm and the frame bracket. Getting the caster angle just right can make a notable difference in how your Jeep handles, especially after suspension work or if you're trying to dial in your alignment.

Each shim is precisely 1/32 of an inch thick, and they come in a pack of six. The neat part is that they're stackable, so you can combine them to achieve larger caster changes if your alignment needs it. This makes them a flexible option for fine-tuning your front-end alignment without needing more complex components. They fit right into place, making the adjustment process straightforward for a mechanic.
