No One Does Portals Like GDP
What can you do with the extra ground clearance and torque that GDP gives you? Anything you want. Reinvent your Polaris RZR Trail S 1000 with SuperATV’s 4” GDP Portal Gear Lift—the industry’s best portals. What makes them the best? You get your choice of a 15% or 30% gear reduction along with cast or billet aluminum housing options so you can ride any way you want. If you want the best of the best, you need to upgrade to dual idler gears. They give you the most strength possible.
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.
GDP Lets You Ride How You Want
Mud, rocks, trails, and desert are all perfect for GDP. If you like bounty holes and boulder fields, go with a 30% gear reduction for low-end torque and bigger tires. If you love to keep the pedal down, choose a 15% gear reduction that’s perfect for high speed and tires that aren’t as big. No matter how you ride, GDP has what you need.
Portals Reduce Drivetrain Stress
GDP’s RZR Trail S 1000 Portals put the gear reduction directly in the hub, which is good news for your drivetrain. This placement greatly reduces the amount of stress placed on your axles, differential, prop shaft, and transmission. Because portals don’t make those parts work overtime, they’ll last longer—which saves you money in the long run. You’re welcome.
The Pinnacle of Portal Strength
The core of any good portal lift is strength, and that’s something we know a lot about. With more GDPs sold than any other portal system, we have the experience to make them right. Our cast and billet aluminum housings are meticulously designed to maximize durability. Those housings come paired with our advanced steel alloy backing plate that make them unbeatable.
Advanced Gaskets, Seals, and Bearings
