UMI GM G body axle housing Roto-joint
This unit allows full articulation of the GM 4-link rear suspension. By using this unit 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 this unit 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 the USA.
