Power and Performance with GDP
You don’t ride on anyone’s terms but your own. So when it comes to equipping your Polaris RZR Trail S 900 to be more capable, you want options. SuperATV delivers with our GDP 4” Portal Gear Lift. Get your torque back with a 15% or 30% gear reduction and get unbeatable strength with either cast or billet aluminum housings. If you want the toughest possible portals, upgrade to dual idler gears and ride harder than ever.
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.
No Matter How You Ride, GDP Portals Are Built for It
Mud bogging is a whole different game with GDP’s RZR Trail S 900 Portals and a 30% gear reduction. With all that torque, you can plow through mud with massive tires easier than ever. If you prefer riding flat out, you’ll make great use of our 15% gear reduction. You still get plenty of torque, but it’s better suited for going fast on tires that aren’t as huge.
GDP Stresses Your Drivetrain Less
Portal gear lifts 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 Best Strength in the Industry
GDP Portals are tough—really tough. The housings are designed from top to bottom with strength in mind. Plus, they’re backed by ultra-durable backing plates made with an advanced steel alloy that can’t be beat. So whether you choose cast or 6061 billet aluminum housings, you’re getting portals that are built for battle.
