Opt for SuperATV's 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, SuperATV has made its 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 these do. The 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 SuperATV's 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. The housings are stronger by design. SuperATV knows 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 SuperATV's unstoppable backing plates made with an advanced steel alloy.
The 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—SuperATV knows because it tested them
Advanced Gaskets, Seals, and Bearings
The 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!
