3612 – 1978-1996 GM B-Body Extended Length Rear Lower Control Arms, Adjustable

UMI Performance extended length control arms are designed to center the rear wheels of the Impala SS correctly within the wheel well. These control arms feature a 5/8” extension with added adjustment capabilities for precise centering of the rear end. Users can further adjust the length of the control arms by an additional ¼” beyond the initial extension. Made from 1.500” DOM tubing and fully TIG welded for maximum strength, these control arms also provide provisions for attaching a stock or aftermarket sway bar. The sway bar holes are reinforced with a 0.120” steel sleeve that is TIG welded and sanded in place. A billet aluminum spacer is used to attach the sway bar to the control arms in the factory location.

Please note that depending on ride height variations, a longer driveshaft may be necessary when using these extended length control arms. This control arm setup is compatible with UMI Performance weld-in relocation brackets, part #3610. Rotating the sway bar spacer block on top of the control arms allows the relocation brackets to be used while reinstalling the sway bar.

Installation typically takes 1-2 hours using OEM hardware. Installation instructions and new 10.9 grade sway bar hardware are included, with additional mounting hardware available for purchase if needed. These control arms are constructed from 0.120 wall thickness DOM steel tubing, CNC machined for precise tolerances, and come fully assembled with greaseable bushings. They feature 4140 Chrome moly threaded tube adapters and bushing threads, as well as a durable glossy powder coat finish for long-lasting durability.
