SuperATV 4in. Portal Gear Lift for Polaris General

Perfection takes time. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don't do a thing if they're not mated perfectly, though. Didn't think dual idlers mattered? With GDPs quality and experience, they finally do.

GDP Lets You Ride Where You Want

With 15% and 30% gear reduction options available, you can customize your GDP Portals for the kind of riding you actually do. If you've never tackled mud or rocks while riding on portals, you're seriously missing out. GDP Portals with a 30% gear reduction have the torque you need to push big tires through nasty bounty holes and crawl over bigger rocks. Or you can opt for a 15% gear reduction if you like to ride fast in trails and don't need huge tires. You'll still have torque that makes you smile.

Save Your Drivetrain with Portals

Portals put the gear reduction right in the hub, which is a literal lifesaver for some of your vehicles most critical components. Putting the reduction in the hub places less stress on your axles, differential, prop shaft, and transmission, so you can ride harder than stock while causing less wear. Talk about a win-win situation!
