It gives you 4\" of lift and helps you take back your torque with a 15% or 30% gear reduction, so no matter where you ride, you'll be unstoppable. You get your choice of cast or billet aluminum housing and you can opt for dual idler bearings to take strength over the top. Whatever you choose, you'll soon realize there's no trail too intimidating when you're rolling on GDP.\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 Any Rider\u003c\/strong\u003e\u003cbr\u003eIf you thought mudding was fun, just wait until you try it with a 30% gear reduction on Honda Pioneer 520 portals. With bigger tires and more torque, you'll chew through the thick mud that used to slow you down. Our 30% gear reduction is great everywhere, but if you want to maintain more top speed on your UTV, go with 15%. It gives you punchy power without sacrificing your top end.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eA Gear Reduction That Protects Your Drivetrain\u003c\/strong\u003e\u003cbr\u003eWith 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStrength Through and Through\u003c\/strong\u003e\u003cbr\u003eWe've spent years studying, manufacturing, and testing portals. So we know what it takes to make or break them. That's why you won't find housings or backing plates stronger than what we use for our GDP portals. You get the choice of cast or billet aluminum housings to go with your 5\/16\" advanced alloy backing plates.
