Better Gears Our gears are precision ground and made with 9310 billet steel alloy for high strength and high speed. That means they’re cool and quiet even when you’re hammering down the throttle on the road, and they have strength to withstand every ride.
Stronger Housings by Design Trust us when we say we’ve done our research. We’ve seen what makes housings fail—you know, those designs and materials that give off a “what not to do” vibe. And we do the opposite of that. Our housings are stronger, smarter, and more dependable by design. Whether you go with cast or our USA-made and CNC-machined 6061 billet aluminum, you’re getting portal housings that offer unmatched strength and reliability.
- Our housings are reinforced in all the right places
- They’re built with better oil flow and gearing forces in mind
- There are no gimmicks and no vents because vents do more harm than good—we know because we tested them
Advanced Gaskets and Seals Whether you go with cast or billet, both housings use:
- Advanced Thermo-Tork® gaskets with excellent oil resistance and a lower deterioration rate than Kevlar gaskets
- A sealed input gear and double-lipped output seal
- 100% sealing coverage throughout so you can forget about oil leaks
