You get your choice of gear reduction and the option for dual idlers. \u003cbr\u003e \u003cstrong\u003eGDP Portals Are Best in Class\u003c\/strong\u003e\u003cbr\u003eA portal gear lift is the pinnacle of power and performance, and nobody does it better than GDP. So get SuperATV’s Polaris RZR 900 4″ GDP Portal Gear Lift to take your ride to the next level. You get your choice of 15% or 30% gear reductions and cast or billet aluminum housings. On top of getting your perfect torque, you have the option to upgrade to dual idler gears for ultimate strength.\u003c\/p\u003e\n\u003cp\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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGDP Works for All Kinds of Rides\u003c\/strong\u003e\u003cbr\u003eIf you like getting down and dirty, choose a 30% gear reduction and start flingin’ mud. It gives you low-end torque for massive tires and power to push through peanut butter mud. If you prefer to drive flat out, choose a 15% gear reduction. It still gives you a bunch of torque for bigger tires but leaves plenty of your top-end speed. No matter where or how you ride, we’ve got you covered.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePortals Are Easy on Your Drivetrain\u003c\/strong\u003e\u003cbr\u003eThese RZR 900 portals put the gear reduction in the hub and makes life easier for the entire drivetrain. Your axles maintain factory geometry and work less. Your axles, prop shaft, differential, and transmission are under less stress. That means longer lasting components, and a lift that doesn’t destroy your machine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesigned with Long-Lasting Strength\u003c\/strong\u003e\u003cbr\u003eWe dare you to find something stronger than GDP portals.
