What is the purpose of these shims?

These shims are used to make fine adjustments to your vehicle's suspension alignment, particularly for camber and caster. The tapered opening allows for a range of adjustment sizes, helping you achieve precise alignment specifications.

What does the zinc coating do?

The zinc coating is applied to help resist corrosion. This means the shims will hold up better over time, especially in environments where road salt or moisture is a concern.

How many shims are included?

Each box contains 25 shims. This quantity is generally sufficient for most alignment jobs, providing enough pieces for necessary adjustments.

Product Details

SPC Performance is well-known for making parts that help get your alignment dialed in just right. These DUO FIT SHIMS are a perfect example of that focus. If you're working on an alignment and need to make fine adjustments, especially in the front suspension where camber and caster are critical, these shims are a solid option.

What makes these shims stand out is their tapered opening. This design means a single shim can cover a wider range of adjustment, from 7/16 inches up to 1/2 inch. This can simplify the process, as you might need fewer different shim sizes to achieve your target alignment specs. They're also zinc coated, which helps them stand up to corrosion, so they'll hold up well even in areas where road salt is common. Each shim is 1/16 inch thick, giving you a precise way to make those small but important adjustments.

You get 25 shims in a box, which should be plenty for most alignment jobs. Remember to always refer to your vehicle's service manual for the correct alignment procedures and specifications.
