UMI's boxed lower control arms feature Roto-Joint technology for smooth and bind-free performance, providing a comfortable and quiet ride quality. These control arms are constructed from 0.120” wall thickness rectangular tubing, with CNC machined bushing holders and MIG welded end caps to prevent debris build-up. They have provisions for adding a stock or aftermarket rear sway bar, with reinforced sway bar holes for durability.
The Roto-Joints offer 28 degrees of unrestricted movement, reducing control arm flex and bushing deflection for improved traction and handling. The delrin-lined Roto-Joints eliminate wheel hop and provide precision handling, outperforming rubber and polyurethane bushings. The control arms are suitable for street, auto cross, or road race applications while absorbing shock and reducing road noise.
UMI's Roto-Joints allow for 28 degrees of rotation and unrestricted movement, preventing suspension bind and improving traction. The 4140 chrome moly spherical ball and delrin race offer wear resistance and durability, with the ability to be adjusted and rebuilt as needed using a spanner wrench.
The spanner wrench is used for adjusting and disassembling Roto-Joints in UMI Performance products, ensuring proper maintenance and longevity of the control arms.
