What is the difference between a 3-link and a 4-link rear suspension setup?

A 3-link setup typically uses one upper control arm and two lower control arms to locate the rear axle. A 4-link setup uses two upper and two lower control arms. This mount is useful for adapting a 4-link system to a chassis originally equipped with a 3-link.

Does this mount come with all the necessary hardware?

Yes, this rear upper control arm mount includes new Grade 8 hardware to complete the installation. You will need to verify if your vehicle uses one or two upper control arms, as this part is sold individually.

What is the benefit of the powder coat finish?

The bright red or gloss black powder coat finish provides a durable layer of protection against corrosion and abrasion. This helps the mount withstand the elements and maintain its appearance over time.

Product Details

UMI Performance is known for making well-built suspension and chassis components for classic American cars. This rear upper control arm mount is designed to replace the original bracket on your 1959-1964 GM B-Body vehicle, like your Chevrolet Bel Air. It's a solid piece to use when the factory mount has rusted away or if you're upgrading to a 12-bolt 4-link system on a car that originally had a 3-link setup.

This bracket is CNC machined from 0.188-inch thick steel plate, so it's built strong. It's precision bent to fit right and comes with a durable red or gloss black powder coat finish to resist corrosion. UMI includes new Grade 8 hardware to make installation straightforward. Remember that some big block cars came with a 4-link setup, while six-cylinder and small block cars typically used a 3-link. This mount is sold individually, so make sure you know if your car uses one or two upper control arms.
