What is the benefit of UMI's Roto-Joint technology?

UMI's Roto-Joint allows for 28 degrees of unrestricted rotation in your suspension. This helps prevent suspension bind, leading to improved traction and a reduction in wheel hop compared to stock bushings.

Are these control arms adjustable or rebuildable?

Yes, the Roto-Joints are adjustable and 100% rebuildable. If the Delrin race wears over time, an adjuster ring can be tightened, or the race can be replaced entirely.

Do these control arms come with all necessary hardware for installation?

These control arms are designed to use your vehicle's original hardware for installation. They are shipped fully assembled and ready to bolt on.

Product Details

The UMI Performance lower control arms for your 1982-2002 F-Body Camaro are built around their unique Roto-Joint technology. This system allows for a full 28 degrees of rotation, giving your suspension the unrestricted movement it needs to articulate properly, especially during hard cornering or when dealing with uneven road surfaces. This is a significant improvement over stock rubber bushings, which can bind up and lead to issues like wheel hop.

At the heart of the Roto-Joint is a 4140 chromoly spherical ball, hard chrome plated for wear resistance, that rotates within a CNC-machined Delrin race. Delrin is chosen for its strength and resistance to wear, ensuring a long service life. The housing is also constructed from strong 4140 chromoly with TIG-welded construction for durability. These control arms are shipped fully assembled and ready to install, using your vehicle's original hardware. The Roto-Joints are greaseable and can be adjusted or rebuilt if needed, making them a practical choice for both street and track use.

This set features Roto-Joints on both ends of each control arm for maximum suspension articulation. The combination of the Roto-Joint's design and the Delrin race helps absorb road noise and shock, contributing to a quieter and more comfortable ride than you might expect from a performance suspension component.
