GDP Portals Rock
The temptation to drown your stock RZR
in a mud pit is almost irresistible, but you’re worried about getting stuck.
Get SuperATV’s Polaris RZR Pro R 4″ Portal Gear Lift so you can take on the
bounty hole without batting an eyelash. You get your choice of a 15% or 30%
gear reduction and cast or billet aluminum housing—oh, and don’t forget the
dual idler gears option. We built these portals to get you through even the
slickest, deepest mud with ease.
Dual Idler Gears?
Perfection doesn’t happen overnight. We dedicated years of research and
development to make our dual idler gear portals unlike anything you’ve ever
seen before. Adding a second gear in the portal box spreads the force over
twice as much surface area for better, more reliable torque transfer. But
these aren’t any old dual idler gears. We use precision CNC grinding to ensure
a perfect fit. We use industry-leading 9310 steel alloy for quality and
durability too. They’re the strongest gear set you can get.
Pick Your Gear Reduction
We let you choose your gear
reduction to customize your ride down to the smallest detail. A 15% gear
reduction is perfect for adding strength for the occasional mud pit while
preserving your rig’s top speed. If you want to add huge tires, a 30% gear
reduction will help you get the power you need to keep those monsters turning.
No matter how you ride, we’ve got the perfect gear reduction for your Pro R.
Protect Your Drivetrain with GDP
Because the
gear reduction is located in the wheel hub, our GDP portals protect the more
expensive drivetrain parts from unnecessary stress. GDP portals work overtime
to save those parts—like your axles, differential, prop shaft, and
transmission—from all the stress required to move giant tires.
Built Tough with Aluminum and Steel
We built these
portals to last. Our cast and billet aluminum housings are designed for
maximum durability even under the worst abuse. We pair our housings with
advanced steel alloy backing plates to make them completely matchless in
strength and quality.
- 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
