Polaris RZR S 1000 RackBoss 2.0 Rack and Pinion for Big Lift Kits

Your RZR's steering system takes a beating on the trail. Stock rack and pinion assemblies wear down fast when you're running bigger tires, heavy lift kits, and pushing hard over rocky terrain. That's where a beefier replacement comes in—one that won't give up after a season or two of real use.

The RackBoss 2.0 for your Polaris RZR S 1000 is built to handle what you throw at it. It uses a dual-bushing setup (called X24 technology) that cuts internal wear by more than half compared to the factory piece. The PTFE bushings sit on both sides of the assembly, controlling the movement between gears and springs so things don't rattle loose or break down. You also get a grease fitting right on the unit, so you can keep it flushed out if you're regularly splashing through mud and water.

This kit includes a brand-new rack and pinion assembly plus a set of beefed-up tie rods. Those tie rods are built from solid steel with a 1-inch diameter and Z-shaped bend. Each end has different thread sizes—16 mm on one side for the rack, 3/4 inch on the other for the rod itself. Heim joints (tough ball-and-socket connectors) handle the articulation, and reinforced gussets brace the bend for extra strength.
