UMI Performance 65-66 GM B-Body Upper Control Arm Mount

This upper control arm mount is CNC machined from 0.188-inch thick steel plate, offering a solid replacement for rusted factory mounts on your 1965-1966 GM B-body vehicle. It's designed to attach the rear upper control arm to the chassis, and it's a popular choice when you need to reuse a solid bracket or when installing a 12-bolt 4-link setup on a vehicle that originally had a 3-link rear suspension.

The precision bending ensures it fits right, and the mount includes new Grade 8 hardware for a straightforward installation. A notable feature is the instant center adjustment capability; by changing the position of the upper control arm in the bracket's different holes, you can fine-tune your suspension's geometry. The center hole matches the factory location, making it easy to get started, and the bracket is finished in a bright red or gloss black powder coat to resist corrosion.

Remember, this mount is sold individually. Most six-cylinder and small-block vehicles came with a 3-link rear suspension, typically using one upper control arm per side, while big-block vehicles used a 4-link setup. Be sure to check your specific vehicle's configuration to order the correct quantity.
