Its an evolution of our original RackBoss that uses X24 Tech to reduce wear by over 50%. Put SuperATVs RackBoss 2.0 Rack and Pinion on your Polaris RZR 900 to ride hard and get silly without ruining your steering system. Its built for big lifts, big tires, and treacherous rides.

Less Wear and Tear with Our Dual-Bushing Design

What makes RackBoss 2.0 so good at preventing slop? Its engineered with X24 Techheavy-duty PTFE bushings at both ends of the rack that remove play from the internals. Reducing play also keeps the tension spring nearly motionless. With little to no unintended internal movement, this rack can turn massive tires through heavy rides and hard hits and still stay in like-new condition for years longer than the next best rack. And with the built-in grease fitting, you can push fresh grease through after you go deep in mud or water.
