How many upper control arms does my vehicle need?

This part is sold individually. Many six-cylinder and small-block V8 equipped vehicles used a 3-link rear suspension with one upper control arm. Big-block vehicles typically used a 4-link setup and may require two upper control arms. It's best to confirm your vehicle's specific configuration before ordering.

What is the benefit of polyurethane bushings over stock rubber?

Polyurethane bushings are more rigid than stock rubber bushings, which means they deflect less under load. This reduced deflection helps minimize wheel hop during acceleration and improves the consistency of your rear suspension during cornering, leading to better handling and traction.

Does this control arm come with all the necessary hardware for installation?

This listing is for the control arm itself, which includes the polyurethane bushings. It is designed as a bolt-on replacement, but you should refer to the manufacturer's installation instructions for details on any additional hardware that may be required or recommended for installation.

Product Details

Starting with 1.750" x 0.120" DOM mild steel tubing, these upper control arms from UMI Performance are built to handle the demands of your classic GM B-body. Stock control arms can flex and deflect, especially under acceleration, leading to wheel hop and less predictable handling. These arms are designed to minimize that deflection, giving you a more solid connection between your chassis and rear axle.

The arms feature CNC machined bushing holders and TIG welded construction for a strong, well-built assembly. They come equipped with grease-able Energy Suspension polyurethane bushings, which offer a noticeable improvement in ride quality and reduced traction loss compared to worn-out rubber bushings. This bolt-on replacement is a popular choice for street cars, drag racers, and restoration projects looking to improve cornering and track consistency.

Remember, this part is sold individually, so be sure to check if your specific vehicle configuration uses one or two upper control arms. This upgrade is a straightforward way to get better performance from your classic Chevy.
