Polaris Sportsman XP 6″ Portal Gear Lift


Polaris Sportsman XP 6″ Portal Gear Lift



Gen 3 Portals are Geared for All
SuperATV’s GDP 6” Portal Gear Lift for the Polaris Sportsman XP gives you a lift and a gear reduction in one box. Get the clearance to run bigger tires and the torque you need to turn them. The lift and gear reduction are in the hub which means they maintain suspension geometry and reduce drivetrain stress. Customize by choosing between a 30% or 45% gear reduction and selecting a cast or billet aluminum housing. GDP portals are truly geared for all. See what customer Goose Bellows has to say about our 6” portals on his Instagram famous Can-Am Maverick XRS, aka Lil Buckin’ Crazy.

45%–Perfect for Mud
Install big 6” portals with a 45% gear reduction to get clearance for huge tires and a massive boost in torque. It’ll turn your monster tires like they’re stock and take your Sportsman XP through the biggest, thickest mud holes you can find. These portals redefine power — and they’re really good at flingin’ mud.

45%–Perfect for Rocks
A 6” portal box with a 45% gear reduction gives you tons of torque to crawl over any rock or boulder you can find. With that much power, rock shelves will feel like speed bumps and boulders feel like pebbles. With 6” of clearance, you can run bigger tires and spend less time getting stuck.

30%–Perfect for Everything
A 30% gear reduction lets you turn bigger tires and gives you the versatility to run mud, dominate trails and hills, and maintain high speed on the road. It gets your power to the ground to let your ATV do more on every ride.

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 get you through every nasty mud hole and rock garden.

Stronger Housings by Design
If you’re looking for the strongest gear boxes you can get, look no further. We make our gear boxes by design, and the hundreds of thousands of ride hours prove that our housings have what it takes to go hard. Whether you want a gorgeous, USA-made billet aluminum housing or a cast aluminum housing, you know you’re getting stronger housings made with unmatched experience.

  • 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
