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

If you're working on a 1964-1967 GM A-Body car like a Chevelle, GTO, or Skylark, these UMI Performance tubular rear control arms are a solid upgrade over stock. Factory control arms can flex and deflect, especially with worn bushings, which hurts traction and makes the car feel loose. These tubular arms are built to be strong and precise, helping to put power down more effectively and improve how the car handles through turns.

They're constructed from 1.625-inch diameter mild steel tubing with a 0.120-inch wall thickness, offering a strong foundation. Inside, you'll find well-built polyurethane bushings that offer better deflection resistance than the original rubber ones, and they even come with grease fittings to keep them lubricated. This setup helps reduce wheel hop, which is common on these cars, and contributes to more consistent handling on the street or at the track. The powder coat finish adds durability and a clean look, and the whole assembly is TIG and MIG welded for strength.

Installation is straightforward, designed as a direct bolt-on replacement that typically takes about an hour and doesn't require any drilling. You can use your original hardware to mount them up, making it a simple swap to get improved rear suspension performance.
