UMI's on-car adjustable lower control arms for 1982–2002 GM F-Body cars feature a rebuildable Roto-Joint paired with polyurethane chassis bushings to provide bind-free movement and street-friendly compliance. The system permits length adjustment to fit larger tires or center aftermarket rear ends; Roto-Joints use 4140 chrome-moly hardware and a delrin race for durability. Arms arrive TIG-welded, powder coated and ready to install.
