Gen 3 Portals—Best on the Market
You didn't get your RZR Turbo R for leisurely rides—you got it to climb the biggest dunes and thrash through deepest bounty holes. SuperATV"s GDP 6" Portal Gear Lift gives your Polaris RZR Turbo R a lift and a gear reduction, all in one box. GDP is different from the rest. These portals were born from blood, sweat, and countless hours of real-world testing—all so you can enjoy your Turbo R to the fullest.
Dual Idler? What's That?
Years of research and testing have given these portals a reputation that speaks for itself. Thanks to our clever engineering, we've figured out how to place a second idler gear in the portal box. That means the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Our perfected combination of precision grinding and 9310 steel alloy is what sets these dual idler portals apart from anything else on the market.
However You Ride, GDP Makes it Better
GDP Portals are designed to tackle any challenge and accomplish any task. From dunes to trails to mud, you'll never look back with a GDP Portal Gear Lift. Get a smaller 30% reduction for faster rides that still pack plenty of torque. Bigger tires and rougher 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 your torque back so your monster build can still rip harder than the rest.
Don't Strain Your Drivetrain
Portals place the gear reduction in the hub, meaning less stress is put on your drivetrain. Your machine's most vital parts won't have to work overtime to make up for the extra 6" of lift. Your axles, prop shaft, differential, and transmission will thank you, and they'll last longer, too.
Cast or Billet Housings for Ultimate Strength
GDP is the strongest and most trusted portal gear system in existence. Our cast and billet aluminum housings are the thickest and strongest you can get, and they're backed by unmatched real-world experience, so you can be confident that you're getting a kickass product. Throw in our 5/16" backing plates made from an advanced steel alloy and you're left with downright unstoppable Polaris RZR Turbo R portals.
- 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
