Description
Gen 3 Portals are Geared for All
SuperATV’s GDP 6”
Portal Gear Lift for the Polaris RZR XP 900 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 RZR through the biggest, thickest mud holes you can find. These
portals are built for power — and they can fling the mud to prove it.
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 clear nastier rock gardens without getting winched.
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 make your UTV more capable in all terrains.

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
We know how to make a
strong portal housing by design, so no matter what we make them out of,
they’re the best. Lucky for you, GDP housing designs are backed by unmatched
real-world experience, so you can be confident that you’re getting a kick-ass
housing whether you choose cast or USA-made billet aluminum.
- 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
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
