UMI Performance 65-88 GM A/G-Body Roto-Joint Rear End Housing Bushings
The UMI P/N 2999 adds the finishing touch to allow full articulation of the GM 4-link rear suspension. By using 2999 and either Roto-Joints or rod ends in the other six locations, your 4-link will move bind-free whether it be autocross transition, road race cornering or just back road corner carving. These Roto-Joints install with a gentle press fit and are retained by a spiral retaining ring. The 6061-T6 aluminum housing is pre-greased with Synco Super Lube and will provide smooth motion for years to come. 100% manufactured in Philipsburg, PA-USA.

Before we built suspension parts, Utmost Machine manufactured precision components for major brands such as Bell+Howell, Corning Asahi, and Sony. Our product line has changed over the years but our dedication to quality remains the same. In-House Manufacturing...If we can make it in our shop, we do. This means we control almost every aspect of the product, resulting in suspension components suitable for attacking the high banks of Daytona or more importantly, hauling your family. Engineered to Race... UMI Performance was founded in 2002 as a father/son business developing performance parts for GM and Ford products. They quickly began to focus on suspension upgrades for both older and late model muscle cars, and have become a leader in replacement and high-performance suspension components, from individual parts to entire kits. Our product engineers and sales team are racers. We race what we sell and use that experience to design and develop our products. 100% Made in USA... Our dedicated craftsmen and craftswomen use only the highest quality USA sourced raw materials to build components worthy of your dream car.
