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

UMI Performance is known for building solid suspension components that improve vehicle handling and durability. These non-adjustable upper control arms are a prime example, designed specifically for the 1968-1972 A-Body platform, and they fit a range of popular models like the Buick Skylark, Chevrolet Chevelle, and Pontiac GTO. They replace your factory arms to offer a bind-free performance and a quieter ride, which is a big deal for anyone looking to get more out of their classic muscle car.

What sets these arms apart is UMI's Roto-Joint technology. Think of it like a spherical rod end, but with streetable qualities. It allows for a generous 28 degrees of rotation, letting your suspension move freely without binding. This articulation, combined with the delrin race that doesn't deflect like softer bushings, helps reduce wheel hop and improves traction, especially during spirited driving or on the track. The Roto-Joint itself is built tough with a 4140 chromoly, hard chrome-plated ball that rotates in a durable delrin race, all housed in a TIG-welded chromoly threaded body. This construction is made to resist wear from hard driving and many miles. The arms themselves are constructed from beefy 1.500" x 0.120" DOM tubing with thick 0.250" mounting plates, finished with a durable powder coat.

These control arms come fully assembled with the Roto-Joints installed and ready to bolt on, using your OEM hardware. The Roto-Joints are also greaseable, making maintenance straightforward. If you're looking to improve your classic A-Body's handling and reduce unwanted wheel hop, these UMI control arms are a well-built option.
