Description
Take Your RZR Turbo R to the Next Level
Do the most
with your RZR Turbo R by installing a set of 8” GDP Portals. They give you the
ground clearance you need to fit up to 42” tires, and you can select your own
gear reduction—45%, 60%, or 70% . If that’s not enough to impress you, choose
our most extreme portal lift with dual idlers. With our GDP portals installed,
you’ll defiently be the talk of the trail.
What is a Dual
Idler?
Perfecting our secret sauce didn’t come naturally—we’ve
spent years researching and testing our work. Today we’re proud to say that
our dual idler isn’t like anything on the market. We placed a second idler
gear in the portal box, so the load gets spread over twice as much surface
area giving you more reliable torque transfer. And the strongest gear set
you’ve ever seen. How does it work? We’ve engineerd the two idler gears to be
mated perfectly by our precision CNC grinding techniques. Not to mention, our
gears are made from the industry’s toughest 9310 steel alloy.
We Know All About Mud
Everyone knows you can’t truly
enjoy mud pits if you’re not rolling on GDP. The extra lift will keep you from
getting swamped in deep bogs and also give you room for bigger tires. And
don’t even get us started on the torque boost! Our gear reduction—either 45%,
60%, or 70%—will have you cutting through the mud like it’s nothing.
A Gear Reduction That Protects Your Drivetrain
With the
gear reduction all the way at the hub, you get reduced stress on your axles,
differential, prop shaft, and transmission. That means your components will
last longer than stock even though you’re riding harder.

The Strongest Portal Housings and Backing Plates You Can
Get
We use an advanced steel alloy for our backing plates.
They’re stronger than chromoly and at 5/16 inches thick, they’ll stand up to
anything and everything the trail throws at you. We’ve also spent years
tweaking and honing our portal housings to make them as strong as possible.
With tens of thousands of housings in the wild proving their strength every
weekend, you know you’re getting the best. So go with cast or super-sleek,
USA-made billet aluminum—either way, you’re getting the best.
- 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
