Gear Down and Go Big
We know you like to go big, and it doesn’t get any bigger than an 8” GDP Portal Gear Lift. That’s a heck of a lot of room for huge 40” tires and a ton of torque, thanks to the 45%, 60%, or 70% gear reduction. Get ultimate strength by pairing our 70% reduction with dual idler gears that never back down from a fight. Your Polaris RZR XP 1000 will feel like a whole new machine when you’re towering over the competition and throwing up rooster tails better than anybody else.
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 do. 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.
45%, 60%, and 70% Gear Reductions Are Perfect for Mud
What’s the first thing you need if you’re serious about mud? A big lift. The second thing? Some big Assassinator Tires of course. And after that? The gear reduction to turn them. Our 8” portals have got you covered. You’ll have room to install huge 40” tires. And the 45, 60, and 70% gear reductions give you the most extreme torque to tear up the bounty hole. That way, you can push through and ride over deeper, thicker mud holes and take home the bounty.
A Gear Reduction That Protects Your Drivetrain
Portals put the gear reduction right in the hub. That puts it after your entire drivetrain and it makes your drivetrain work less and wear less. That means more miles out of your axles, differential, transmission, and prop shafts.
Learn more about how tire size and gear reduction can unleash your machine’s potential.
Stronger Housings and Backing Plates by Design
GDP Portals are the strongest you can get because we know how to make them tough. We’ve been using them and refining them for years. Whether you go with cast or USA-made, 6061 billet aluminum housings (which look awesome), you’ll get unmatched strength through superior design. Combine that with 5/16” backing plates made with an advanced steel alloy, and you’ve got the brawniest portals on the market.
Advanced Gaskets, Seals, and Bearings Our portals use:
Frame Stiffener Required
You need a SuperATV Frame Stiffener with your RZR 1000 Portals. The stock frame just doesn't have what it takes. Bump too hard and the OEM frame will bend. Trust us—we've done it. A frame stiffener reinforces your frame enough to let you ride your 8" portals with monster tires and no worries.
Top-Rated Customer Service
Still need a little help getting exactly what you need? We’ve got a dedicated team just for portal support. Give us a call so we can get the perfect set of portals in your hands today.
