UMI Performance 78-96 GM B-Body Boxed Lower Control Arms- Poly/Roto-Joint

UMI Performance is known for making well-built suspension components that improve the performance of classic American cars. If you're looking to upgrade the rear suspension on your 1978-1996 GM B-Body vehicle, like a Chevrolet Caprice or Buick Roadmaster, these boxed lower control arms are a solid option. They're designed to give you better traction and handling by reducing unwanted movement in the suspension.

These control arms are fabricated from strong 3-inch by 1-1/2-inch rectangular steel tubing with a 0.120-inch wall thickness, and they're MIG and TIG welded for added durability. The real standout feature is the Roto-Joint technology. This setup uses a delrin-lined spherical joint that allows for 28 degrees of movement without binding, which helps reduce wheel hop and improves how your car puts power down. You also get greaseable polyurethane bushings on one end for a comfortable ride, and the sway bar mounts are reinforced to handle the extra stress. They come fully assembled with the Roto-Joints installed, ready to bolt on using your original hardware.

The Roto-Joints are also adjustable and rebuildable, meaning you can maintain them for long-term use. A spanner wrench is included to help with any adjustments or disassembly you might need down the road. This combination of strong construction and advanced joint technology makes these control arms a great choice for street performance applications.
