UMI Performance 64-72 GM A-Body Adjustable Lower Control Arms Rod Ends CrMo

If you're looking to dial in your classic GM A-Body's rear suspension, especially for wider tire fitment or to correct alignment after installing aftermarket rear ends, these adjustable lower control arms from UMI Performance are a solid option. They're built for both race applications and spirited street driving, designed to eliminate rear suspension bind that can come with stock rubber bushings. This means your suspension can move more freely, leading to improved handling and a more consistent contact patch.

These control arms are constructed from strong 1.250" x 0.095" 4130 CrMo steel tubing and TIG welded for maximum strength, making them lighter and stronger than the factory arms. The key feature is the double adjustment capability, allowing you to easily change the length of the control arm by up to an inch longer or shorter right on the car. This is incredibly useful for centering your rear end or gaining clearance for larger tires. They come pre-set to the factory length, so you can start there and adjust as needed. The arms use high-load capacity, Teflon-lined spherical rod ends, which offer a solid connection and eliminate the compliance found in rubber bushings. UMI also machines their own 4130 CrMo tube adaptors for these rod ends, adding durability to the adjustment threads.

These control arms are designed for aftermarket sway bars that don't attach to the control arm itself, so they don't have sway bar mounting holes. They reuse factory hardware, though UMI offers a new hardware kit if you prefer. They fit a wide range of 1964-1972 GM A-Body vehicles, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Oldsmobile Cutlass. They are manufactured in Philipsburg, PA, USA.
