Detroit Speed's tubular lower control arms replace stock lower control arms on 1978-1988 G-Body platforms. Features include a robust tubular design with gussets and cross brace, Delrin™ bushings with steel housings and crush tubes, and a black powder coated finish. The geometry features include additional positive caster in the 1978-1988 G-Body control arms compared to stock. Any OEM shock and spring package will fit. These tubular lower control arms are shipped complete with lower ball joints, steering stops, and are ready to install on your car.  Also included with the G-Body control arms are the heavy duty precision end links that connect the lower control arms to the front sway bar. The lower control arms have CNC machined tube ends for precision fits. The arms are then TIG welded in a fixture for accuracy and repeatability of geometry.Optimize your performance with a Detroit Speed shock or spring package.
