UMI Performance 4062-1-B Corner Max Lower Front A-Arms are direct bolt-in tubular suspension upgrades for 1964-1972 GM A-Body vehicles.

They have a double shear coilover mount for standard ½” rod end shocks (with spacers) and a double shear sway bar mount compatible with UMI P/N 4035, 4067, and many factory eyelet-style sway bars. Delrin bushings ensure smooth travel and reduced deflection. Can be paired with UMI P/N 4056 for up to 10 degrees of caster. Manufactured in Philipsburg, PA, USA, with North American raw materials, precision-bent DOM tubing, laser-cut components, and a durable powder coat finish.
