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 Try as you might, you won’t find housings stronger than what we use on our GDP portals. Our housings are smarter, stronger, and more reliable by design. So whether you choose cast or USA-made and CNC-machined 6061 billet aluminum, you’re getting housings that offer unmatched strength and dependability. We’ve got the experience and the riders on the trail to back it up.
- 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
