UMI Performance 64-67 GM A-Body Adjustable Upper Control Arms - Ultimate Arms

If you're looking to dial in the rear suspension on your 1964-1967 GM A-Body, these Ultimate Arms from UMI Performance are a solid choice. They're designed to let you easily adjust your pinion angle, which is crucial for getting better traction and reducing that annoying wheel hop, especially if you've lowered your car. This adjustability is a big deal when you're trying to fine-tune your car's performance at the track or even just for street driving.

UMI didn't cut any corners building these. They use strong 4140 chromoly steel for the threaded tube adapters and the solid adjuster, which is heat-treated for extra durability. The TIG welded construction means these arms are well-built and ready to handle the stress of performance driving. Plus, the QA1 Teflon-lined spherical rod ends allow for smooth, bind-free operation, which is a noticeable improvement over stock components. You can make adjustments right on the car by simply loosening a couple of jam nuts and turning the adjuster, making it convenient to dial in your setup at the garage or the track.

These arms fit a wide range of classic GM vehicles from 1964 to 1967, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. They come with a durable powder coat finish and CNC machined aluminum step bushings for a clean installation.
