What is the main benefit of using double adjustable lower control arms?

Double adjustable control arms allow you to fine-tune your rear suspension alignment for improved handling and to eliminate rear-end bind. This is especially beneficial for drag racing, as it helps put power down more consistently and reduces unwanted suspension movement.

Are these control arms suitable for street use, or are they strictly for racing?

While built with race-ready features like spherical rod ends, these control arms are designed to handle high torque and horsepower, making them excellent for drag racing. They also offer improved handling for performance street applications by reducing suspension bind.

Do these control arms come with all the necessary hardware for installation?

These control arms are designed to use your vehicle's OEM hardware for installation. They are a bolt-on component and do not require drilling, making installation straightforward.

Product Details

If you're looking to get the most performance out of your classic GM A-Body, especially for drag racing or serious handling, these double adjustable lower control arms from UMI Performance are a solid choice. They're built to handle high torque and horsepower, and they eliminate the rear-end bind that can happen with stock rubber or polyurethane bushings. This means you get more consistent power to the ground and better control when you're pushing your car hard.

These arms are constructed from strong 0.120" x 1.500" DOM steel tubing with TIG welded fabrication for a much stronger joint than typical MIG welding. The tube adapters are CNC machined from 4140 Chrome Moly for improved strength and thread durability, an area where some competitors cut costs. They feature QA1 Endura Series Teflon-lined spherical rod ends, which allow for bind-free operation during high-angle maneuvers and are perfect for drag racing applications. The sway bar mounting holes are also reinforced with a steel sleeve for added strength. Installation is straightforward, using your vehicle's original hardware and requiring no drilling.

These control arms fit a wide range of GM A-Body vehicles from 1964-1972, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. They come with a durable powder coat finish and are designed to work with your OEM sway bar and hardware.
