UMI lower A-arms for 1978–1988 G-body trucks use DOM tubing, CNC notched ends, and TIG-welded construction to replace worn stamped components. Equipped with greaseable fluted polyurethane bushings, premium ball joints and polyurethane bump stops, these arms bolt on to improve handling and tire life. They fit factory spindles and are compatible with factory or lowering springs and common coilover setups.
