SuperATV 6in. Portal Gear Lift for Yamaha Viking

When you get SuperATV's GDP 6 Portal Gear Lift for your Yamaha Viking, you get to pick a 30%, 45%, or 60% gear reduction and cast or billet aluminum housings. Plus, you can choose to upgrade to dual idlers for unparalleled strength. Whatever you choose, there's no better way to get some more clearance under you while also changing your gear ratio.

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.

Ride Any Way You Want

Love mud? You haven't experienced mud until you've tackled it with a GDP portal gear lift. The extra six inches of clearance give you room for massive mud tires and the 45% or 60% gear reduction keeps you from getting stuck. Love trails and wide-open speed? Opt for SuperATV 30% gear reduction that still delivers tons of torque but maintains a higher top speed.

A Gear Reduction That Protects Your Drivetrain

That puts less stress on your drivetrain, which means your machines most vital parts can do their job without acquiring premature wear. You'll ride easy knowing that your prop shaft, axles, diff, and transmission are in good hands.
