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.

The Toughest Portals in the Industry
It takes a lot of hard work to make GDP Portal Gear Lifts the strongest in the world. We've put in years of research and testing to bring you portals that are strong enough to keep up with even the most rugged off-road lifestyle. Between our beefed up cast or billet aluminum housings and our advanced alloy backing plates, there's nothing that will stop you.

• Our housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Enhance with Portal Bloodgear oil formulated for GDP Portals
• There are no gimmicks and no vents because vents do more harm than goodwe know because we tested them

Advanced Gaskets, Seals, and Bearings
Our portals use:

• Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates
• A sealed input gear and double-lipped output seal
• 100% sealing coverage throughout so you can forget about oil leaks
• Double-angular contact output bearings to prevent premature wear
• Roller idler and drive bearings to maintain perfect gear meshing
