Gen 3 Portals Are Unbeatable GDP didn™t make the first side-by-side portal kit on the market”just the first kit that anybody gave a damn about. With Gen 3 GDP Portals, you get to choose between 30%, 45% and 60% gear reductions, and you can add dual idlers. So you get to decide just how wild you want to make your Polaris Ranger XP 570. GDP is blazing the trail with quality and versatility. No matter how you ride, GDP Portals will 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 Every Riding Style GDP Portal Gear Lifts are designed to enhance every rider's experience. They™re not just for mudders or rock crawlers”they™re perfect for trails, dunes, deserts, and more. 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. A Gear Reduction That Protects Your Drivetrain Thanks to the fact that the gear reduction goes right in the hub, portals reduce the stress on your axles, differential, prop shaft, and transmission. That makes this a lift that™s easier on your drivetrain than riding stock, and your most vital parts will last longer, too. It™s a win-win. The Toughest Portal Lift You Can Get We know how you ride.
