This kit does not include a panhard bar.

The upper and lower rear arms hold the axle in place front to back and control how it rotates under acceleration and braking. Every bump, landing and throttle input goes through their pivots.

A uniball is a spherical bearing. It lets the arm pivot freely as the axle articulates, without the give of a rubber bushing, so the axle stays where the arms put it. A machined billet arm is one solid piece with no seams.

The urethane wobble stopper at the front mounts keeps the arms in alignment.
