Show original supplier description

The UMI Performance 402116 Rear Control Arms Kit provides enhanced performance for 1968-1972 GM A-Body vehicles. Constructed from durable 3" x 1-1/2" mild steel rectangular tubing with a 1/8" wall thickness, these fully boxed lower control arms feature CNC machined radius ends and bushing holders. This design minimizes suspension deflection, leading to improved handling and reduced wheel hop. The kit includes greaseable polyurethane bushings with zinc-plated sleeves for a quiet and comfortable ride, and the MIG-welded bushing holders ensure durability. The black powder coat finish provides a long-lasting, factory-like appearance. This kit includes both the lower control arms (4021) and non-adjustable upper control arms (4016). The product is proudly made in Philipsburg, PA, USA, utilizing North American raw materials and precision manufacturing processes. This kit fits a wide range of GM A-Body vehicles from 1968-1972, including various Buick, Chevrolet, Oldsmobile, and Pontiac models. It also specifically fits the 1971-1972 GMC Sprint.
