UMI's F-Body lower control arms for 1982–2002 GM applications pair a greaseable polyurethane bushing with a swivel Roto-Joint to deliver bind-free movement, improved traction and reduced wheel hop. Made from 1.500" x 0.120" DOM tubing, the Roto-Joint features a 4140 chrome-moly spherical ball rotating in a CNC-machined delrin race. Adjustable and rebuildable, these arms ship assembled with OEM-fitment hardware.
