GDP Portals Give You Strength and Performance SuperATV™s GDP 4 Portal Gear Lift for the Honda Pioneer 500 gives you power and performance that you can™t get anywhere else. Get it with a 15% or 30% gear reduction to give you the punchy torque you need, and pair it with your choice of housing to get your perfect portal. If you want unbeatable strength, opt for our dual-idler configuration. You have the power to make work easier and weekends more fun. 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 All Kinds of Rides Get a 30% gear reduction and start flingin™ mud. With a massive boost to torque, you can chew through the thickest bounty holes. It™s also perfect for rocks where you get the torque you need to crawl over boulders like they™re not even there. Usually stick to chores and trails? Go with a 15% gear reduction. You™ll have the clearance and power you need to push through ruts and ditches easily all while towing a trailer full of supplies. Plus, you™ll still have enough speed to cruise down the road and take on trails easily. A Gear Reduction That Protects Your Drivetrain With portal lifts, the gear reduction is placed in the hub instead of in the transmission. This means your drivetrain doesn™t have to work as hard, so those important components will last longer. Of all the benefits of a portal gear lift, reduced stress on your axles, differential, prop shaft, and transmission is definitely at the top of the list.
