What is DOM steel tubing?

DOM stands for Drawn Over Mandrel. It's a type of steel tubing that is manufactured using a cold-drawing process, which results in a more consistent wall thickness and a smoother internal surface compared to standard welded tubing. This makes it stronger and more durable for performance suspension components.

What is the benefit of polyurethane bushings over rubber?

Polyurethane bushings are much stiffer than stock rubber bushings. This stiffness reduces flex and deflection under load, allowing for better power transfer to the tires and a more direct, responsive feel from the suspension. BMR's design also ensures proper lubrication for quiet operation.

Does this kit include all the necessary hardware for installation?

This kit includes the control arms and reinforcement braces with their associated polyurethane bushings. It is recommended to refer to the manufacturer's installation instructions for a complete list of required hardware and any additional components you may need for installation.

Product Details

Starting with heavy-duty 1.50-inch diameter, 0.120-inch wall DOM steel tubing for the lower control arms, BMR Suspension has built a rear suspension kit designed to handle serious performance demands. This kit is a solid choice for anyone looking to improve their 1964-1967 GM A-body's launch characteristics, reduce wheel hop, and gain more consistent cornering. The stock stamped steel control arms with soft rubber bushings tend to flex and absorb power, but this BMR kit replaces them with components built for transferring power directly to the tires.

The RSK007 kit includes lower control arms, upper control arms, and control arm reinforcement braces. The upper control arms are constructed from 1.625-inch diameter, 0.120-inch wall DOM steel tubing, providing the strength needed for compression loads. The reinforcement braces, made from 1.0-inch diameter, 0.156-inch wall steel tubing, help minimize frame deflection by tying the upper and lower control arm mounts together. Inside the control arms, you'll find greasable, 95-durometer polyurethane bushings. These bushings offer a much more solid and responsive feel compared to the original rubber ones. BMR's unique internal fluting design keeps grease within the bushing, even under significant load, and directs it to the thrust surface for quiet, reliable operation over time.

This kit is well-suited for street performance, drag racing, and handling applications, offering a noticeable improvement in how your classic A-body puts power down and handles corners. It fits a range of popular vehicles including the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark from 1964-1967. While this kit is non-adjustable, it provides a significant upgrade over stock components for a more connected driving experience.
