Description
Get More Out of Your Pro S with GDP Portals
If you could
get more power and performance from your Polaris RZR Pro S, why would you say
no? With SuperATV’s 4” GDP Portal Gear Lift, you get a lift and gear reduction
built into one package. Our GDP Portals come in 15% or 30% gear reductions
with a choice of either cast or billet aluminum housing. Plus, the 4” lift
gives you clearance to tackle bigger obstacles and fit larger tires. You’ll
feel the difference every time you hit the gas.
What Is a
Dual Idler?
After years of perfecting them, our dual idler gear
portals are built for serious strength. The second idler gear helps spread the
load for better torque transfer and durability. With precise CNC grinding and
tough 9310 steel, these gears are made to last. Perfect engineering and
precision mean our dual idlers are the game changer you’ve been waiting for.
Gear Reduction for Peak Performance
Choose a
gear reduction that fits your ride. Go with a 15% reduction for faster speeds
and solid torque, or ramp it up to 30% for bigger tires and tackling rougher
trails. It’s the perfect way to customize your machine to match your style.
Reduce Wear on Your Drivetrain
GDP Portals for
the Polaris RZR Pro S give you a lift and gear reduction right at the wheel
hub. This setup helps protect your drivetrain and keeps your axles at factory
angles, which reduces wear and tear on your CVs for a more durable ride.
The Strongest Portals on the Market
The last thing
you need when you’re out in your Polaris RZR Pro S is a breakdown. That’s why
we designed our cast and 6061 billet aluminum housing to handle tough
conditions. They’re backed by our advanced steel backing plates for unmatched
strength.
- 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
