UMI's tubular upper control arms feature Roto-Joint technology for smooth, bind-free performance and a comfortable ride quality. The Roto-Joint design offers 28 degrees of unrestricted movement, allowing for improved handling and precision. The delrin race lining the spherical ball absorbs shock and road noise, making for a quiet and smooth operation on any street or track. These control arms are constructed of 1.500” x 0.120” DOM tubing and feature .250” thick CNC machined mounting plates for added durability.
The Roto-Joint technology allows for rotation and unrestricted movement throughout the suspension, preventing bind and improving traction. The spherical ball, made of 4140 chrome moly, rotates in a delrin race for wear resistance and durability. The delrin material offers high resistance against wear and great tensile strength. The housing of the Roto-Joint features 4140 chrome moly threads for strength and durability. The Roto-Joint is adjustable and rebuildable, ensuring long-lasting performance.
The spanner wrench is used for adjusting and disassembling Roto-Joints for maintenance and rebuilding purposes. It allows for tightening the adjusting ring to apply more pressure to the delrin race inside the Roto-Joint. The spanner wrench is essential for maintaining optimal performance of UMI Performance products.
