GDP Gives You The Portals You Need You™ve never really seen your Polaris RZR S 1000 come alive until you™ve put SuperATV™s 4 GDP Portal Gear Lift on it. It™s available with 15% or 30% gear reductions and cast or billet housings. And for all those riders that can tear up any kit, you can opt for dual idler gears that take durability to another level. Nobody does portals like GDP. 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. Wherever You Ride, GDP Can Make it Better GDP has gear reduction options to fit any ride style. Get a 30% gear reduction and start flingin™ mud and crawling over rocks. With a massive boost to torque, you can turn bigger tires that tear through anything. With a 15% gear reduction, you can take on the trail less traveled. You™ll keep that high speed for serpentine tracks but that extra torque will carry you over hills and creeks where others get stuck. Either way, it™s a game changer. Portals Give You a Longer-Lasting Drivetrain Portals put the gear reduction right in the hub, which is a literal lifesaver for some of your vehicle™s most critical components. Putting the reduction in the hub places less stress on your axles, differential, prop shaft, and transmission, so you can ride harder than stock while causing less wear. Talk about a win-win situation! The Beefiest Portals You Can Get When it comes to all-out durability, nobody does RZR S 1000 portals better than GDP.
