SPC Performance 55-57 Chevrolet Tri 5 Front Adjustable Upper Control Arm

When you're working on a classic like a 1955-1957 Chevrolet Bel Air, getting the alignment just right is key to making it handle the way you want. These adjustable upper control arms from SPC Performance are built to help you dial in your front-end alignment for improved handling and performance. They allow you to adjust both camber and caster, which are critical angles for how your tires meet the road.

These arms feature a well-built steel cross shaft. You can choose between street-style pivots with OE-style rubber bushings for a comfortable ride with minimal deflection, or race-style pivots with Delrin inserts for a firmer connection. This adjustability means you can compensate for suspension modifications or simply get your classic car tracking straighter and cornering with more confidence. The ball joint plate is also part of the assembly, making it a comprehensive solution for upgrading your front suspension geometry.
