What is DOM mild steel tubing?

DOM stands for Drawn Over Mandrel. It's a type of steel tubing that is manufactured using a process that results in a more consistent wall thickness and a smoother internal surface compared to standard welded tubing. This makes it a strong and reliable material for suspension components.

Do these control arms come with hardware?

This listing is for the control arm itself, which includes the bushings. You will need to reuse your original hardware or source new hardware separately for installation.

How do I know if I need one or two upper control arms?

The number of upper control arms your vehicle uses depends on its original suspension setup. Most six-cylinder and small-block vehicles were equipped with a 3-link rear suspension, requiring one upper arm. Big-block vehicles typically used a 4-link setup, which requires two upper arms.

Product Details

Starting with 1.750" x 0.120" DOM mild steel tubing, these UMI Performance rear upper control arms are built to handle more power and improve your GM B-body's handling. Stock control arms can deflect under load, leading to lost traction and vague steering. These tubular arms replace that weak stamped steel with a strong, well-built unit designed to minimize wheel hop and keep your tires planted.

The arms feature CNC machined bushing holders for a precise fit, and they come equipped with greaseable Energy Suspension polyurethane bushings. These poly bushings offer a noticeable improvement over the stock rubber, providing better control without an overly harsh ride. The TIG welded construction ensures solid joints, and a durable powder coat finish helps protect against corrosion. Whether you're building a street cruiser, a drag car, or a restored classic, these control arms are a solid option to improve your vehicle's rear suspension performance.

Remember, this part is sold individually. You'll need to check your specific vehicle's setup to determine if you need one or two upper control arms. Most six-cylinder and small-block vehicles use a 3-link rear suspension, while big-block cars typically have a 4-link setup.
