Get SuperATV's Polaris RZR Pro R 4\" Portal Gear Lift so you can take on the bounty hole without batting an eyelash. You get your choice of a 15% or 30% gear reduction and cast or billet aluminum housing oh, and don't forget the dual idler gears option. We built these portals to get you through even the slickest, deepest mud with ease.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDual Idler Gears \u003c\/strong\u003e\u003cbr\u003ePerfection doesn't happen overnight. We dedicated years of research and development to make our dual idler gear portals unlike anything you've ever seen before. Adding a second gear in the portal box spreads the force over twice as much surface area for better, more reliable torque transfer. But these aren't any old dual idler gears. We use precision CNC grinding to ensure a perfect fit. We use industry-leading 9310 steel alloy for quality and durability too. They're the strongest gear set you can get. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePick Your Gear Reduction\u003c\/strong\u003e\u003cbr\u003eWe let you choose your gear reduction to customize your ride down to the smallest detail. A 15% gear reduction is perfect for adding strength for the occasional mud pit while preserving your rig's top speed. If you want to add huge tires, a 30% gear reduction will help you get the power you need to keep those monsters turning. No matter how you ride, we've got the perfect gear reduction for your Pro R.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProtect Your Drivetrain with GDP\u003c\/strong\u003e\u003cbr\u003eBecause the gear reduction is located in the wheel hub, our GDP portals protect the more expensive drivetrain parts from unnecessary stress.
