Polaris Ranger XD 1500 8" GDP Portals

Geared for Maximum Performance
Whether at work or at play, the ultimate rider has SuperATV’s GDP Portals on their machine. Your Polaris Ranger XD 1500 will have the power it needs to dominate any terrain with an 8” GDP Portal Gear Lift. You get 8” of lift and an all-in-one gear reduction, giving you the ability to run larger tires and become the master of off-roading. We offer them in a 45%, 60% or 70% gear reduction. For maximum strength upgrade from cast to billet aluminum housing.

What Is a Dual Idler?
Perfection takes time. After years of research and development, we’ve 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 don’t do a thing if they’re not mated perfectly, though. 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.

The Power to Conquer
Take on any terrain confidently with SuperATV’s GDP Portals. Your Ranger XD 1500 will have more ground clearance, which allows you to run larger tires. You can choose between a 45%, 60% or 70% gear reduction for boosted torque. You’ll be able to turn large tires like they were stock size.

Reduce Stress on Your Drivetrain
With GDP Portals, the gear reduction is in the wheel hub instead of the transmission. This gives your drivetrain extra protection. It puts less strain on your axles, prop shaft, differential, and transmission. This could save you from future costly repairs.

Unmatched Strength
No one wants to spend money on a product that can’t hold up. SuperATV’s GDP Portals are offered with cast or billet aluminum housing. Combine that with our 5/16” backing plates made of advanced steel alloy and you’re getting the best portals in the industry. Abuse them as much as you want—they can handle it. Plus, they're backed by a lifetime warranty because we know accidents happen.

• 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
