UMI Performance, Inc is proud to introduce our P/N 2999 GM A/G body axle housing Roto-joint. The 2999 allows 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 UMI has you covered. For street use, they also pair well with our hybrid poly/Roto combination arms - poly for comfort and Roto-Joint for performance. These Roto-Joints install with a gentle press fit and are retained by an easy to install 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.
