SPC Performance 64-72 GM A Body Front Adjustable Upper Control Arm

If you're working on a classic GM A Body like a Chevelle, GTO, or Skylark from 1964 through 1972, and you need to dial in your front-end alignment, these adjustable upper control arms from SPC Performance are a solid option. They replace your stock arms and give you the ability to make precise adjustments to camber and caster, which is crucial for getting your suspension set up just right, especially if you've lowered the vehicle or are running wider tires. These arms are built with OE-style pivots that minimize deflection, meaning they hold their alignment settings well under load.

What sets these apart is the adjustable sleeve design, which allows for easy and accurate alignment corrections right at the control arm. This is a big help for mechanics and DIYers alike, as it means you can fine-tune your alignment without needing to rely solely on eccentric bolts or shims, which can sometimes be less precise or more difficult to adjust. The included mid-size plate is designed to work with the factory mounting points, making installation more straightforward. These are well-built components designed to help you achieve improved handling and tire wear characteristics on a wide range of GM A Body models.
