Roto-Joint Technology:

UMI's Roto-Joint design combines the performance of spherical rod ends with the streetability of softer bushings. The hard chrome plated spherical ball rotates within a precision CNC-machined delrin race, which provides superior wear resistance and tensile strength while maintaining quiet operation. Unlike rubber or polyurethane bushings, the delrin race doesn't deflect, resulting in improved traction and significant reduction in wheel hop. The adjustable design allows you to tighten the adjuster ring as the delrin wears, extending service life.

Applications:

These adjustable control arms are ideal for vehicles requiring precise rear end positioning, especially when installing larger tires or aftermarket rear ends. The on-car adjustability allows you to move the rear axle forward or backward to achieve proper tire clearance and centering. Suitable for street cruising, drag racing, autocross, and road racing applications.
