C4 Corvette Caster / Camber Upper Control Arm Conical Spacer Shim Kit

C4 Corvette Upper Control Arm Alignment Spacer Kit

Designed for C4 Corvette front suspensions, these stainless steel spacers provide additional camber adjustment beyond what is possible with the discontinued factory spacers.

Factory spacers typically provide only about 0.5° of additional negative camber, and on some vehicles they are not sufficient to achieve even 0° camber. These replacement spacers retain the correct conical seating surface that mates with the upper control arm cross shaft, maintaining proper clamping force while accommodating minor component misalignment.

**Features**

* Provides increased negative camber adjustment compared to factory spacers.
* Available in 0.050-inch thickness increments for precise caster and camber adjustments.
* Manufactured from marine-grade stainless steel for corrosion resistance and long service life.
* Suitable for both stock C4 Corvettes and C4 suspension swaps.

**Installation**

Installation typically takes about 30 minutes. Support the suspension with a floor jack, measure the existing shim stack with a digital caliper, and replace the spacers as needed.

Detailed installation instructions are included to simplify setup before final alignment.
