The UMI Performance adjustable rear upper control arm for 2005–2010 Ford Mustang uses a spherical Roto-Joint and greaseable delrin race to allow 28 degrees of unrestricted movement for bind-free articulation. This direct bolt-on replacement is built from DOM steel tubing, is on-car adjustable with a chromoly adjuster, ships assembled and includes spacers to reduce oversized chassis mount holes and stop rear-end clunking.
