Description
Portals are geared for all, and that means we’re not putting anyone in a box. Choose a 15% or a 30% gear reduction to match your ride style. Love going big and going deep? Get 30% gear reduction for maximum torque and bigger tires. Prefer trail riding? Get a 15% gear reduction. Need ultimate strength? Opt for our dual idler configuration. The choice is yours. Ride your way wherever you want. Let GDP take you where no one else can go.
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
Love mud? The deeper you go, the more you’ll realize how much torque a 30% portal gear reduction really gives you. Plus that extra ground clearance will keep you from getting swamped. Portals plus mud just makes sense. For trails, desert, and dunes, check out our 15% gear reduction that maintains a higher top speed while still giving you punchy torque.
A Gear Reduction That Protects Your Drivetrain
Portals have their gear reduction right in the hub. That makes this gear reduction reduce the stress on your axles, differential, Prop shaft, and transmission. You can ride harder than stock and cause less wear. It’s a win-win, and a recipe for fun.
Stronger Housings by Design
You think you can find better housings that GDP housings? Think again. Our housings are stronger by design. We know what makes a housing break and why. That’s why whether you choose cast or USA-made 6061 billet aluminum with a dead sexy CNC-machined finish, you’re getting a kick-ass housing with unmatched strength and reliability. Plus, they’re supported by our unstoppable backing plates made with an advanced steel alloy.
- 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
Complete the Package with a Frame Stiffener
Portals and monster tires are fun, but they can place additional stress on your machine’s frame. To make your suspension bulletproof, don’t forget to add a SuperATV Frame Stiffener when you check out!

Vehicle Information
Yamaha Viking 700 Side-by-Side (2014-2026)
The Yamaha Viking 700, produced from 2014 to 2026, is a robust and reliable utility side-by-side vehicle. It is powered by a 686cc liquid-cooled, 4-stroke, SOHC, fuel-injected single-cylinder engine, delivering optimal torque and an estimated 50 horsepower. Known for its Ultramatic V-belt transmission and On-Command 4WD system, the Viking 700 is designed for both work and recreation, ensuring consistent performance throughout a decade of production. While the 686cc engine displacement remained consistent, the Viking 700 underwent a significant engine and chassis overhaul upon its introduction in 2014, featuring a higher compression piston and new intake and exhaust systems. In 2015, the six-seater Viking VI model was introduced, expanding the lineup. The Viking VI was later discontinued for the 2026 model year, streamlining the offering to three-seater configurations. Electric Power Steering (EPS) versions became more prevalent over the years. Q: How can I ensure parts fit my Yamaha Viking 700?
