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 tubing. This makes it stronger and more durable for suspension components.

How do I know if my vehicle has a 3-link or 4-link rear suspension?

Generally, six-cylinder and most small-block engine vehicles were equipped with a 3-link rear suspension. Big-block engine vehicles typically used a 4-link setup. It's best to visually inspect your vehicle's rear suspension to confirm the number of upper control arms.

Do these control arms come with all the necessary hardware?

This listing is for the control arm itself, which includes the polyurethane bushings and bushing holders. It is designed as a direct bolt-on replacement, but you should reuse your vehicle's original mounting hardware or consult the manufacturer's instructions for any specific hardware requirements.

Product Details

Starting with 1.750" x 0.120" DOM mild steel tubing, these rear upper control arms from UMI Performance are built to handle more than stock arms. The factory control arms on your GM B-body can be a weak point, especially when you're looking for better traction or a more consistent feel on the street or at the track. These arms are designed as a direct bolt-on replacement to help minimize wheel hop and improve how your car corners.

Inside the DOM steel tubing, you'll find CNC machined bushing holders that accept grease-able Energy Suspension polyurethane bushings. These polyurethane bushings offer a notable improvement over the stock rubber ones, helping to reduce unwanted flex and keep your rear suspension working more predictably. The entire assembly is TIG welded for solid construction and finished with a durable powder coat to look good and resist corrosion. Whether you're restoring a classic, building a street machine, or heading to the drag strip, these arms are a solid choice for an improved rear suspension feel.

Keep in mind that GM B-body vehicles can have either a 3-link or 4-link rear suspension setup. Six-cylinder and most small-block vehicles typically came with a 3-link, while big-block cars often used a 4-link. This part is sold individually, so be sure to order the correct quantity for your specific suspension setup.
