Our portals let you customize the way you ride by picking your gear reduction (30%, 45%, or 60%) and your housing material (cast or billet aluminum). With a boost in torque, room for monster tires, and the option for dual idlers, your Wolverine will be a force to be reckoned with on any terrain.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat is a Dual Idler  \u003c\/strong\u003e\u003cbr\u003ePerfection 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\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePerfect for Rides of Any Kind\u003c\/strong\u003e\u003cbr\u003eWherever you go, GDP Portals will make it better. You can't go mud riding without seeing a portal gear lift or two. That's because GDP Portals with 45% or 60% gear reduction are perfect for mud. Portals give you enough clearance to run massive mud tires and a gear reduction to turn them. If mud's not your style, go with a 30% gear reduction for smaller tires and balanced torque for trails.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eA Gear Reduction That Protects Your Drivetrain\u003c\/strong\u003e\u003cbr\u003ePortals put the gear reduction directly in the hub. This greatly reduces the amount of stress placed on your axles, differential, prop shaft, and transmission, so they'll last longer even though you're riding harder than ever. It's a win-win situation.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eGDP Portals Are Stronger\u003c\/strong\u003e\u003cbr\u003eWe've been designing and testing portals for years, so we know a thing or two about making them tough.
