Gen 3 Portals are Geared for All GDP didn™t make the first side-by-side portal kit on the market”just the first kit that anybody gave a damn about. Your Ranger XP 900 is a workhorse, but we all know it™s got an untapped wild side. That™s where SuperATV™s 6 GDP Portal Gear Lift comes in. Pair awesome ground clearance with your choice of 30%, 45%, or 60% gear reductions to boost your power to the ground®. And you can maximize your strength and performance by opting for dual idler gears. You™ll turn your mild Ranger into a wild party wagon. GDP is refined by the fire of hard rides and hard work”now let it redefine your Ranger. 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. Perfect for all Riding Styles GDP Portal Gear Lifts are for riders that never give up. A rock wall is just a challenge to overcome. Whether you face miles of desert and dunes, wild technical trails, or peanut butter mud up to your ears, GDP is built for it. Get a smaller 30% reduction for faster rides that still pack plenty of torque. Bigger tires for rocks or rough 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 a lift and your torque back so you can build whatever machine you need. A Gear Reduction That Protects Your Drivetrain Portals put the gear reduction in the hub instead of the transmission, so it reduces the stress on your axles, differential, prop shaft, and transmission. That means your components will last longer than a stock machine. Yes, really. Ride hard”your machine won™t mind. GDP Portals Give You Unmatched Strength You™re going big and you™re making it bold.
