UMI Performance 68-72 A-Body Adjustable Upper Control Arms- w/ Roto-Joint

If you're working on a 1968-1972 A-Body vehicle and looking to improve its handling and adjustability, these adjustable upper control arms from UMI Performance are a solid option. They replace your stock arms and feature UMI's Roto-Joint spherical bearing, which significantly reduces unwanted suspension movement. This means less deflection for a more responsive feel on the street, at the strip, or when carving corners, and it also helps reduce wheel hop during hard launches.

These arms are built tough with a mix of TIG and MIG welding and feature 1/4" thick CNC laser-cut mounting pads. The Roto-Joints work with UMI's own CrMo adjuster, allowing you to fine-tune your pinion angle easily while the arms are still bolted to the car. This on-car adjustability makes setting up your rear end much simpler. The arms come with a durable powder coat finish and are made in the USA.

Installation is straightforward, typically taking 1-2 hours with basic hand tools, and they are designed to bolt directly onto various rear end housings used across many GM A-Body models from the late 60s and early 70s.
