Heavy Duty Control Arm Upper & Lower Tubular A Arms GM 64-72 Chevelle GTO Malibu This listing is for a brand new set of heavy duty tubular Upper and Lower A-Arms for 1964-1972 Chevelle, Monte Carlo, Malibu, El Camino, GTO, Tempest, LeMans, and Cutlass. Suspension geometry is improved over stock by increasing camber gain and improving roll camber. These control arms are redesigned for better steering and suspension. The control arms feature steel cross shafts which incorporate aluminum bushings. The upper control arms also utilize greaseable bushings which make for increased stiffness over stock to provide more consistent and precise handling. The bushings also have machined bevel, stainless washers, and stainless lock nuts. The upper control arms also feature powder coated gloss black machined tube ends for precision fits which are assembled with ball joints. The tubular lower control arms replace stock lower control arms. These new tubular lower control arms feature a robust tubular design with gussets and cross brace, bushings with steel housings and crush tubes, and a powder coated gloss black finish. The conventional lower coil spring pocket features a stamped steel pocket with a positive spring locating feature and nutserts for the shock lower attachment.

The arms handle pressures that would fold the OEM control arms in half. These control arms are designed for cars that are being lowered.
