Our portals are built on the back of unmatched dedication and experience. We weren't the first to put a portal on a Ranger”just the first to do it with a kit anybody gave a damn about. Get GDP Portals and reinvent 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. Ride Them Anywhere Portals dominate mud, but they™re not just for mud. They destroy rock gardens, but they™re not just for rocks. Ride them anywhere you want any way you want, and you™ll have power and performance like you never thought possible. Get a 15% gear reduction for faster rides with enough torque to get wild. If you want the ultimate geared-down, torqued-up ride for monster tires, go with a 30% gear reduction. Grab dual idlers on either if you need portals that can survive the apocalypse. You know who you are. A Gear Reduction That Protects Your Drivetrain Portal gear lifts put the gear reduction right in the hub, meaning your drivetrain isn™t put under a bunch of unnecessary stress. This means your axles, differential, prop shaft, and transmission are safe from early wear and tear. You™ll be able to ride harder and longer, and your machine™s most vital parts will thank us.
