Gen 3 Portals Break the Rules GDP didn™t make the first side-by-side portal kit on the market”just the first kit that anybody gave a damn about. We make Gen 3 portals that work for any kind of rider, whether you like to bury your Ranger in mud or just haul feed. With SuperATV™s GDP 6 Portal Gear Lift for the Polaris Ranger 1000, you can choose between a 30%, 45%, and 60% gear reduction. You can even add dual idler gears for bulletproof strength. Our GDP Portals raise the bar and break all the rules to give you a Polaris Ranger 1000 experience you™ll never forget. 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 You never know where adventure will lead, and sometimes your next ride takes you to unexpected places. GDP is built with wild adventure in mind, from trails to dunes to mud. Whether you™re climbing cliffs in Moab or exploring your property, a GDP Portal Gear Lift will enhance your ride. 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 your torque back so your monster build can still rip harder than the rest.
