SuperATV Polaris Ranger XP 900 6" Portal Gear Lift

SuperATV Polaris Ranger XP 900 6" Portal Gear Lift

Gen 3 Portals are Geared for All
GDP didn’t make the first side-by-side portal kit on the market—just the first kit that anybody gave a damn about. Your Ranger XP 900 is a workhorse, but it’s got an untapped wild side.

That’s where SuperATV’s 6" GDP Portal Gear Lift comes in. Pair awesome ground clearance with your choice of 30%, 45%, or 60% gear reductions to boost your power to the ground.

You can maximize your strength and performance by opting for dual idler gears. Turn your mild Ranger into a wild party wagon. GDP is refined by the fire of hard rides and hard work—now let it redefine your Ranger.

What is a Dual Idler?
Perfection takes time. After years of R&D, we’ve made our dual idler gear portals unlike any other.

By placing a second idler gear in the portal box, the load spreads 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 perfectly mated. Precision CNC grinding ensures ours are. 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.

Perfect for All Riding Styles
GDP Portal Gear Lifts are for riders who never give up. A rock wall is just a challenge to overcome.

Whether you face miles of desert, dunes, wild technical trails, or peanut butter mud up to your ears, GDP is built for it.

Get a smaller 30% reduction for faster rides that still pack plenty of torque. Bigger tires for rocks or rough terrain require a 45% gear reduction. Build the ultimate mudder with a 60% reduction.

Then take your strength further with dual idler gears. Portals give you a lift and your torque back so you can build whatever machine you need.

A Gear Reduction That Protects Your Drivetrain
Portals put the gear reduction in the hub instead of the transmission, reducing stress on your axles, differential, prop shaft, and transmission.

That means your components will last longer than stock. Yes, really. Ride hard—your machine won’t mind.

GDP Portals Give You Unmatched Strength
You’re going big and bold. Your Polaris Ranger XP 900 deserves the best, so we made GDP Portals the strongest on the planet.

Our cast and billet aluminum housings deliver unmatched strength. Combined with 5/16" backing plates made from an advanced steel alloy, these portals are unstoppable.

• Housings reinforced for gear retention and optimized for oil flow

• Advanced steel alloy backing plates stronger than chromoly

• Enhance with Portal Blood gear oil formulated for GDP Portals

• No gimmicks or vents—because vents do more harm than good (tested and proven)

Advanced Gaskets, Seals, and Bearings
Our portals use:

• Advanced Thermo-Tork gaskets and O-rings with excellent oil resistance and low deterioration

• Sealed input gear and double-lipped output seal

• 100% sealing coverage so you can forget oil leaks

• Double-angular contact output bearings to prevent premature wear

• Roller idler and drive bearings for perfect gear meshing

Protect Your Ranger with a Frame Stiffener
Consider adding a frame stiffener if you want to push your machine hard without worrying about frame damage.

GDP brings extra ground clearance, bigger tires, and monstrous torque that can stretch your UTV beyond its comfort zone.
