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

When you're working on your 1968-1972 A-Body, these UMI Performance upper control arms are what you get in the box: a pair of fully assembled control arms featuring UMI's Roto-Joint technology. These aren't just standard replacements; they're built to give your suspension more freedom to move, which can make a real difference in how your car handles, especially when you're pushing it a bit. The Roto-Joints are designed to allow for a generous amount of rotation, helping to prevent your suspension from binding up during hard cornering or acceleration. This bind-free movement can lead to improved traction and a noticeable reduction in wheel hop, making your car feel more planted and responsive.

What sets these control arms apart is the Roto-Joint technology itself. It uses a 4140 chromoly ball, hard chrome plated for wear resistance, that rotates within a CNC-machined Delrin race. Delrin is chosen for its strength and wear resistance, offering a balance between the articulation of a spherical rod end and the streetable comfort of a bushing. The housing is also made from strong 4140 chromoly, TIG welded for durability. These arms are constructed from beefy 1.500" x 0.120" DOM tubing with 0.250" thick mounting plates, finished with a durable powder coat. They are designed as a direct bolt-on replacement, using your vehicle's original hardware, and are ready to install right out of the box. The Roto-Joints are greaseable, making maintenance straightforward for a quiet and smooth ride on the street.

These control arms fit a range of classic vehicles, including models like the Buick Skylark, Chevrolet Chevelle, and Pontiac GTO from the late 60s and early 70s. While they are designed for performance, the Roto-Joints are also built to provide a comfortable ride quality on the street. If you plan on adjusting the Roto-Joints over time as the Delrin race wears, UMI offers an optional spanner wrench to help with that process.
