For Hardcore Riders
If tough trails, crazy hills, and top speeds sound like your idea of a good time, what are you doing still running your OEM rack and pinion? Upgrade to a steering system that can’t be beat with SuperATV’s RackBoss Heavy-Duty Rack and Pinion for the Polaris RZR Trail S 1000. With larger housings and unbeatable chromoly tie rod ends, this kit is designed to put up with the crazy off-road abuse you live for. Say goodbye to sloppy steering and hello to a controlled and more confident ride.

Bulletproof Strength
If you haven’t noticed, we don’t skimp when it comes to aftermarket upgrades. Everything we make is backed by research, expertise, and precision, and this rack and pinion is no exception. With a 65% larger housing, 15% bigger rack gear, and wear-resistant Teflon bushing, it’s guaranteed to outperform the competition every time. Just look at the numbers—during testing, RackBoss showed no sign of wear or fatigue after 50,000 strokes, while our competitor’s product showed obvious wear after only 30,000.

Unbeatable Tie Rod Ends
Your tie rods are only as good as the ends connecting them, which is why this kit comes with heavy-duty 4130 chromoly tie rod ends. They’re oversized, which allows for increased bearing surface area, delivering even more durability. And we finish them with a precision blend of materials and heat treatment for improved functionality.

Z-Bend Rack and Pinion for Big Lifts
For riders who are going big with a 6”+ lift, be sure to select the Z-bend option when checking out. Our Z-bend tie rods feature steel gussets that give you the strength you need to run a big lift kit without overextending your joints. The solid tube of these tie rods is made with 4140 steel and they come with 4130 chromoly tie rod ends for even more of a performance boost.

Kit Includes:
  • Rack and pinion
  • Tie rods with 4130 chromoly tie rod ends
