Polaris Ranger Full Size 570 | 900 6in. Portal Gear Lift with 30% Gear Reduction - Cast Housing

Gen 3 Portals are Geared for All
GDP didnt 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 we all know its got an untapped wild side. Thats where SuperATVs 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®. And you can maximize your strength and performance by opting for dual idler gears. Youll 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 research and development; weve 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 dont do a thing if theyre not mated perfectly; though. Precision CNC grinding ensures ours do. Our gears are made from the industrys toughest 9310 steel alloy. Didnt think dual idlers mattered? With GDPs quality and experience; they finally do.

Perfect for all Riding Styles
GDP Portal Gear Lifts are for riders that never give up. A rock wall is just a challenge to overcome. Whether you face miles of desert and 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 rides require a bigger gear reduction—like 45%. Build the mother of all mudders with a 60% gear reduction. Then take your strength over the top 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; so it reduces the stress on your axles; differential; prop shaft; and transmission. That means your components will last longer than a stock machine. Yes; really. Ride hard—your machine wont mind.

GDP Portals Give You Unmatched Strength
Youre going big and youre making it bold. We know your Polaris Ranger XP 900 deserves the best; so we made GDP Portals the strongest on the planet. Our cast and billet aluminum housings give you unmatched strength. Combine that with 5/16 backing plates made from an advanced steel alloy; and our portals are unstoppable.

• 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

Protect Your Ranger with a Frame Stiffener
Consider adding a frame stiffener if you want to put your foot down without worrying about your frame. GDP brings you extra ground clearance; bigger tires; and monstrous torque that can stretch your UTV beyond its comfort zone.
