UMI Performance 64-67 A-Body Non Adjustable Upper Control Arms- w/ Roto-Joint

If you're working on a 1964-1967 A-Body classic like a Chevelle, GTO, or Skylark, these UMI Performance non-adjustable upper control arms are a solid upgrade. They replace the factory arms and use UMI's Roto-Joint technology, which is designed to give your suspension more freedom to move without binding. This means better handling, especially when you're pushing the car in corners or on the track, and it can also help reduce wheel hop on acceleration.

What makes the Roto-Joints special is the pivot ball design with a greaseable Delrin race. It allows for a significant amount of articulation, up to 28 degrees, which is more than enough for spirited driving. This improved movement helps the suspension work correctly, leading to more precise steering and better road feel. The Delrin race also absorbs road noise and shock, so you get improved performance without sacrificing a comfortable ride. These arms are built tough, made from 1.500-inch x 0.120-inch DOM tubing with thick, CNC-machined mounting plates, and they come fully assembled and ready to bolt on using your original hardware.
