The UMI CornerMax A‑arm and mount kit for 1973–1987 GM C10 trucks brings race‑proven CornerMax geometry and double‑shear coilover‑only mounts to improve handling. It includes a direct bolt‑in upper mount (rivet grinding required), permits spring and shock changes without disassembling ball joints, and accepts most racing coilover assemblies. Adjustable caster and camber, tall ball joints and adjustable steering stops round out the race‑capable package.
