GDP Portals Are the Best Your RZR 900 Can Get GDP didn’t invent the portal gear lift, but we did perfect it. And SuperATV’s GDP 6” Portal Gear Lift for the Polaris RZR 900 is the perfect solution for riders who want taller machines, bigger tires, and unmatched power. Choose a 30%, 45%, or 60% gear reduction for more power to the ground. Boost your strength, power, and performance to the max by choosing dual idler gears. GDP isn’t like the other guys. Our parts are refined through endless blood, sweat, and hard rides. GDP portals will redefine your RZR 900.
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.
A Gear Reduction for Any Kind of Ride Install 6” portals with a 30%, 45%, or 60% gear reduction to get clearance for huge tires and a massive boost in torque. It’ll turn your monster tires like they’re stock and take your RZR 900 through the thickest mud holes, over the tallest hills, and down treacherous trails. These portals are all about torque—and they can make the rooster tails that prove it.
Less Drivetrain Wear than Stock We love that portal gear lifts put the gear reduction directly in the hub. This leads to less stress on your machine’s most vital parts, even through rough riding. Your axles, differential, prop shaft, and transmission will thank you—and they’ll last longer, too.
