UMI Performance 4016-B Rear Tubular Non-Adjustable Upper Control Arms for 1968-1972 GM A-Body

Fits 1968-1972 GM A-Body vehicles including Chevrolet Chevelle, El Camino, and Monte Carlo; Pontiac GTO, LeMans, and Grand Prix; Oldsmobile 442 and Cutlass; and Buick GS and Skylark.

Standard factory control arms are constructed from flimsy stamped steel, which is prone to flexing under load. This deflection leads to inconsistent traction, wheel hop, and poor cornering stability. UMI Performance tubular rear upper control arms provide a rigid, non-adjustable replacement that maintains proper geometry and enhances chassis response for street cruising or track use.

These arms are engineered for durability and precision, featuring CNC-machined tolerances and a combination of TIG and MIG welding. The included polyurethane bushings are equipped with grease fittings to ensure smooth, quiet operation while significantly reducing the compliance found in rubber OE bushings. This direct-fit upgrade installs in approximately one hour using existing factory hardware.
