UMI Performance's tubular front lower control arms replace the factory stamped steel lower arms on 1971 through 1987 GM C10 and C15 fullsize trucks and Suburbans with a stronger, more precise setup. Built from tubular steel with polyurethane bushings, they reduce deflection for sharper steering response and more consistent front end alignment. A red powder coat finish resists corrosion and adds a clean look under the truck. UMI Performance manufactures these control arms in the USA.
