UMI tubular lower control arms for 2005–2014 Ford Mustang use the Roto-Joint swivel design to allow 28° of unrestricted suspension rotation for bind-free performance and improved traction. The delrin race and 4140 chromoly pivot ball reduce deflection compared with soft bushings while maintaining street comfort through a polyurethane chassis bushing. The Roto-Joint is adjustable and serviceable with a spanner wrench; arms are built from 1.250" x 0.120" DOM tubing, fully TIG welded, shipped fully assembled and finished in a durable powder coat.
