Description

UMI's boxed lower control arms utilize their Roto-Joint technology for bind-free performance and a quiet, comfortable ride. They are constructed from 0.120" wall thickness rectangular tubing, CNC machined bushing holders, and MIG welded end caps. They feature reinforced sway bar holes and Spherical Roto-Joints that offer 28 degrees of unrestricted movement. The Delrin lined race absorbs shock and road noise for smooth operation. This set features Roto-Joints on both sides for maximum performance and suspension travel, making them suitable for street and track use.
