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.

Maximized Strength

SuperATV spared no details with RackBoss and worked tie rod end to tie rod end to engineer not only the strongest, but the longest-lasting rack and pinion on the market. You want unbeatable reliability? Try a housing that has 40% more material giving you added strength where it's needed most, so no more cracked housings! You want longevity? Utilizing a 15% bigger rack gear and a wear-resistant Teflon bushing, RackBoss showed no sign of wear or fatigue after 50,000 strokes compared to competition showing obvious wear at 30,000 strokes.

Better Tie Rods for a Big Lift

Big lifts beat the heck out of your tie rods, so you can’t settle for anything but the best. Our Z-bend tie rods are made with solid steel bars and reinforced with hand-welded gussets. They’re big and brawny so you can stay in control of your big lift.
