This allows you to adjust your pinion angle without unbolting the control arm from the vehicle. These control arms feature a spherical rod end which has a hard center section to give excellent control and softer outer bushings to prevent binding.

The rear upper control arms offer a complete bolt-in an installation that replaces the flimsy factory upper control arms using the stock hardware. These adjustable rear upper control arms will eliminate any flex, which means more power to the ground. Steeda also includes the rear differential bushings so you can replace your damaged, worn out differential bushings.
