Bearings That Rock
A portal box is only as strong as the bearings that keep everything moving. That’s why our output bearing is a double-angular contact bearing—it can withstand huge forces and huge torque from any angle without wearing prematurely or breaking. Our idler bearings are bulletproof roller bearings. Trust us—the idler does more work than you think. They’re bearings that are meant to be used and abused ride after ride.
Universal Hubs and Slotted Rotors
Our precision-ground, stainless steel slotted rotors stay cool to give you the braking power you need when you need it. They’re paired with universal hubs that make your life easier. They come with 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs—you can fit wheels built for just about any side-by-side in the world on these hubs. We invented the tapered output shaft that our hubs attach to. It provides a more secure lock that won’t wobble or wear over time.
