UMI Performance 78-88 G-Body Double Adjustable Control Arms- w/ Roto-Joints

When you're working on your 1978-1988 G-Body, like a Buick Regal or Chevy Monte Carlo, and want to dial in your rear suspension, these double adjustable lower control arms from UMI Performance are a solid choice. They let you adjust the length of the control arm, which is key for centering your rear end, especially if you're installing an aftermarket one or trying to fit larger tires without rubbing. This set comes fully assembled and ready to go, featuring UMI's Roto-Joints on both ends.

These control arms are built from 1-1/2 inch DOM tubing and use TIG-welded chromoly threaded adapters for strength. The Roto-Joints are a standout feature, offering a bind-free pivot with 28 degrees of movement. They use a greaseable Delrin race that absorbs shock and road noise, making them quiet enough for daily driving but also providing the low deflection needed for performance driving like auto-cross or drag racing. The threaded ends have left and right-hand threads, so you can easily adjust the length right on the car by loosening the jam nuts and turning the arm. They also include reinforced provisions for mounting a stock or aftermarket sway bar.

Having adjustable control arms is often recommended for aftermarket rear end installations to ensure proper alignment and prevent tire interference. The Roto-Joints offer a significant improvement over stock rubber or aftermarket polyurethane bushings by allowing the suspension to articulate more freely, leading to better handling and precision. This setup is designed for maximum performance and suspension travel while remaining streetable.
