SuperATV RZR S 900 RackBoss 2.0 Rack & Pinion

RackBoss 2.0 Is a New Kind of Rack
Your steering rack will eventually wear down, your steering will get sloppy, and your handling will be unresponsive.. and there used to be nothing you could do about it. RackBoss 2.0 changes all that because it’s the only rack on the market that uses X24 Tech—our unique dual-bushing design that reduces wear by over 50% compared to stock. So accept nothing less than SuperATV’s Polaris RZR S 900 RackBoss 2.0 Rack and Pinion to get durability you can’t find anywhere else no matter how you ride.

Less Wear and Tear with Our Dual-Bushing Design
What makes RackBoss 2.0 so good at preventing slop? It’s engineered with X24 Tech—heavy-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.

Solid Steel Bar Tie Rods
For a beefy tie rod setup, you want to go with solid steel bar tie rods. They’re made with 1” diameter steel bars that are paired with bigger, better tie rods you’ll love—3/4” outer heim joint tie rods and rebuildable inner tie rods that use 3/4” rod threads and 16 mm rack threads. Altogether, they’re built for hard hits, big tires, and wild rides.

Swaged Tube Tie Rods
Our swaged tube tie rods are tough but lightweight. The flared out steel tube design boosts the strength beyond what a standard 7/8” tube would have. Plus, it comes paired with our unbeatable tie rod ends that use 16 mm rack threads and huge 14 mm rod threads. They won’t let you down.

Looking for a More Traditional Rack?
If you don’t need all the benefits of a RackBoss 2.0, you can dial it back to our original, more traditional RackBoss 1.0. It uses the same beefy housing but doesn’t include the extra PTFE bushing. Our RackBoss 1.0 Rack and Pinion comes with steel swaged tubes that are tougher than stock and perfect for casual riders looking for an upgrade. It’s finished with our tough 14 mm inner and outer tie rod ends so you can ride harder without worry.
