Gen 3 Portals are Geared for All
SuperATV’s GDP 4” Portal Gear Lift for the Yamaha Wolverine is the ultimate boost to power and perforamance. Choose from 15% or 30% gear reductions and cast or billet aluminum housings so you can optimize for the kind of riding that you do. Opt for our dual idler configuration to get the strongest portals on the planet.
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
Rocks, trails and mud are no match for a Yamaha Wolverine portal gear lift. A 30% gear reduction gives you tons of torque to turn big tires through mud or over rocks. A 15% gear reduction still gives you punchy torque while letting you get wild with on open throttle on trails and tracks. No matter what you’re doing, there’s a GDP Portal setup that can help.
A Gear Reduction That Protects Your Drivetrain
Because GDP Portals put the gear reduction directly in the hub, your entire drivetrain benefits. Your axles, differential, drive shaft, and transmission all work less and wear less with a portal gear lift. You can put the pedal down and have a blast without wrecking your ride.
Stronger Portals by Design
GDP Portals are built to be unmatched. Our housings are well researched and long tested. And you get a choice—go with cast or USA-made, CNC-machined 6061 billet aluminum. They’re supported by beefy backing plates made of an advanced steel alloy you won’t find in any other portal system. For robust, trail-proven strength, GDP is the only choice.
Advanced Gaskets, Seals, and Bearings
