Description

UMI’s Roto-Joint adjustable rear upper control arms are a durable upgrade for your street or pro-touring car. These control arms are suitable for various driving conditions, including street, strip, or corner carving. The premium spherical joint minimizes suspension deflection, providing a more responsive handling experience, easy pinion angle tuning, and reduced wheel hop. These on-car adjustable upper control arms are designed to handle a wide range of applications, and the combination of Roto-Joints and UMI’s chromoly adjuster ensures strength and performance.
