Power and Performance with GDP
You don’t ride on
anyone’s terms but your own. So when it comes to equipping your Polaris RZR
Trail S 900 to be more capable, you want options. SuperATV delivers with our
GDP 4” Portal Gear Lift. Get your torque back with a 15% or 30% gear reduction
and get unbeatable strength with either cast or billet aluminum housings. If
you want the toughest possible portals, upgrade to dual idler gears and ride
harder than ever.
What is a Dual Idler®?
Perfection takes time. After years of research and development, we’ve made our
dual idler gear portals unlike any other. 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. Precision CNC
grinding ensures ours do. Our gears are made from the industry’s toughest 9310
steel alloy. Didn’t think dual idlers mattered? With GDP’s quality and
experience, they finally do.
No Matter How You Ride, GDP
Portals Are Built for It
Mud bogging is a whole different game
with GDP’s RZR Trail S 900 Portals and a 30% gear reduction. With all that
torque, you can plow through mud with massive tires easier than ever. If you
prefer riding flat out, you’ll make great use of our 15% gear reduction. You
still get plenty of torque, but it’s better suited for going fast on tires
that aren’t as huge.
GDP Stresses Your Drivetrain
Less
Portal gear lifts put the gear reduction directly in the
hub, which is good news for your drivetrain. This placement greatly reduces
the amount of stress placed on your axles, differential, prop shaft, and
transmission. Because portals don’t make those parts work overtime, they’ll
last longer—which saves you money in the long run. You’re welcome.
The Best Strength in the Industry
GDP Portals are
tough—really tough. The housings are designed from top to bottom with strength
in mind. Plus, they’re backed by ultra-durable backing plates made with an
advanced steel alloy that can’t be beat. So whether you choose cast or 6061
billet aluminum housings, you’re getting portals that are built for battle.
- Our housings are reinforced for gear retention and optimized for oil
flow - Advanced steel alloy backing plates are stronger than
chromoly - Enhance with Portal Blood—gear oil formulated for GDP
Portals - There are no gimmicks and no vents because vents do more harm
than good—we know because we tested them
Advanced
Gaskets, Seals, and Bearings
Our portals use:
- Advanced
gaskets and O-rings with excellent oil resistance and low deterioration
rates - A sealed input gear and double-lipped output seal
- 100%
sealing coverage throughout so you can forget about oil leaks - Double-
angular contact output bearings to prevent premature wear - Roller
idler and drive bearings to maintain perfect gear meshing
