SuperATV X2/X4 850 4in. Portal Gear Lift for Yamaha Wolverine

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. Or take your strength over the top by upgrading to dual idlers. With GDP, your Wolverine is limitless.

What Is a Dual Idler®?

Perfection takes time. 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. Didn't think dual idlers mattered? With GDPs quality and experience, they finally do.

Perfect for All Kinds of Rides

Whether you're carving through mountain trails or chest-deep in mud, GDP Portals can take your Wolverine further. 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. SuperATV 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.

• SuperATV housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Enhance with Portal Blood - gear oil formulated for GDP Portals

Advanced Gaskets, Seals, and Bearings

SuperATV 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
