Get Better Steering for Your Big Lift
If you’re riding through extreme conditions with a big lift on a regular basis, that stock steering system is only going to last so long. For big tires, crazy whoops, and tough terrain, you need SuperATV’s RackBoss Heavy-Duty Rack and Pinion. It eliminates sloppy steering and keeps those wild rides from ruining your Polaris RZR 4 900. Every inch of this kit is backed by precision and expertise, giving you the confidence to cut loose any time and any place.

Built to Last
We’ve done our research and performed all the tests, so we know what it takes to engineer the strongest and longest-lasting rack and pinion on the market. With a 65% larger housing, 15% bigger rack gear, and internal Teflon bushing, this kit is downright bulletproof. The proof is in the numbers. During testing, the competition showed obvious wear and fatigue after 30,000 strokes, while RackBoss was still going strong after 50,000.

Unbeatable Tie Rod Ends
With a product this heavy duty and long lasting, the devil’s in the details. In this case, the details are our 4130 chromoly tie rod ends. These heavy-duty ends are oversized, resulting in an increased bearing surface area and all the strength you’ll ever need. We finish them with a precision blend of materials and heat treatment to guarantee years of worry-free riding.

Z-Bend Rack and Pinion for Big Lifts
Your 7-10” lift needs tie rods that can handle bigger suspension and heavier tires. That’s why our Z-bend tie rods are made with solid steel bar and have steel gussets that deliver all the strength you need to go big. The unique bend design is the only way to reach the spindle on your lift without overextending the joints. It’s the beefy RZR 4 900 steering rack you need.
