UMI Performance 64-72 A-Body Boxed Lower Control Arms- Poly/Roto-Joint

UMI's boxed lower control arms feature Roto-Joint technology for bind-free performance and a comfortable ride. Made from 0.120" wall thickness rectangular tubing, these control arms are durable and enhance traction while reducing wheel hop. The Roto-Joints provide 28 degrees of unrestricted movement, enabling precise handling and articulation. The delrin-lined Roto-Joints absorb shock and road noise, ensuring smooth operation on any street or track-driven vehicle.

The control arm set includes polyurethane bushings on one end and UMI's swivel Roto-Joint on the other, making it perfect for street performance. The polyurethane bushings help absorb road noise and shock, while the Roto-Joints prevent suspension bind and improve traction. These control arms are MIG and TIG welded for superior strength and come fully assembled for easy installation. The brilliant powder coat finish guarantees durability and long-lasting performance.

UMI's Roto-Joint technology allows for 28 degrees of unrestricted movement, preventing suspension bind and reducing wheel hop. The construction includes a 4140 chrome moly spherical ball rotating in a delrin race, providing wear resistance and durability. The Roto-Joint is adjustable and fully rebuildable, ensuring longevity and high performance. The included spanner wrench can be used to adjust and disassemble the Roto-Joints for maintenance and rebuilding, allowing you to tighten the adjusting ring for added pressure on the delrin race inside the Roto-Joint, ensuring optimal performance and longevity.
