What is the main benefit of using Roto-Joints in the rear end housing?

Roto-Joints allow your rear suspension to articulate freely without binding. This means the rear axle can move more independently of the chassis, leading to improved handling and responsiveness, especially during cornering.

How are these bushings installed?

These Roto-Joints are designed for a gentle press fit into the rear end housing. They are then secured in place with a spiral retaining ring, making them a manageable installation for many DIYers.

What other suspension components are recommended to be used with these bushings?

For optimal bind-free performance, UMI Performance recommends using these Roto-Joints in conjunction with rod ends or other Roto-Joints in the remaining six suspension locations of your 4-link setup.

Product Details

If you're looking to get the most out of your classic GM A-body or G-body's rear suspension, especially during spirited driving or cornering, these Roto-Joint rear end housing bushings from UMI Performance are a smart addition. They're designed to work with your existing 4-link setup, allowing the rear axle to move more freely and without binding. This is especially noticeable when you're transitioning through turns, whether you're on an autocross course, a road race track, or just enjoying some back road carving.

These bushings are built with a 6061-T6 aluminum housing that's pre-greased with Synco Super Lube, ensuring smooth operation for a long time. They install with a gentle press fit and are secured with a spiral retaining ring, making them a straightforward upgrade for many GM vehicles from 1965 to 1988, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Regal. By using these Roto-Joints along with rod ends or other Roto-Joints in the remaining suspension locations, you create a bind-free 4-link system that responds better to the road.
