SuperATV Yamaha Viking 6" Portal Gear Lift

SuperATV Yamaha Viking 6" Portal Gear Lift

We don’t make assumptions about the way you ride because we know that off-roading is different for everyone. That’s why we don’t build “one size fits all” portals. 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. 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

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 our 30% gear reduction that still delivers tons of torque but maintains a higher top speed.

A Gear Reduction That Protects Your Drivetrain: One of the many reasons we love portal gear lifts is the fact that the gear reduction is built right into the hub. That puts less stress on your drivetrain, which means your machine’s 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.

Stronger Housings by Design: We’ve been researching and designing portals for years, so we know what it takes to make or break them. When you choose our USA-made, CNC-machined billet aluminum housings or you decide to go with cast aluminum, you’re getting beefy portal boxes that are reinforced with 5/16” backing plates made from an advanced steel alloy. They’re built for years of the most extreme riding.

• Our 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
• There are no gimmicks and no vents because vents do more harm than good—we 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
