How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

Description

Get Ultimate Power and Performance
When you’re exploring the toughest trails and the most dangerous terrain, you need parts that can give you an edge. That’s where SuperATV’s 6” GDP Portal Gear Lift comes in. Install it on your Polaris Xpedition to get industry-leading power and performance. With a 6” lift paired with a 30%, 45%, or 60% gear reduction, you get room for massive 34” tires and torque to push through any obstacle.

Dual Idlers for Ultimate Strength
Perfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. They’re made with the industry’s toughest 9310 steel alloy. Two idler gears don’t do a thing if they’re not mated perfectly. Precision CNC grinding ensures that they do. Didn’t think dual idlers mattered? With GDP’s quality and experience, they finally do.

Do Almost Anything with 30%, 45%, and 60% Gear Reductions
Our 6” portals give your Xpedition room to run up to 34” tires. But big tires and tons of overlanding cargo slow you down. That’s where the gear reductions come in. They’re built into the portal hubs and give you a huge boost in torque. All that power means you can turn monster tires, carry heavy gear, and roll over the toughest obstacles with ease.

GDP Portals Save Your Drivetrain
You're not just getting better power and performance when you put GDP Portals on your Polaris Xpedition. You’re getting the only lift that protects your suspension and your drivetrain. It maintains factory suspension angles, and it reduces wear and tear on your drivetrain thanks to the gear reduction in the hub.

Strength and Reliability
Nothing's more important than reliability for an overlanding adventure vehicle like the Polaris Xpedition. That’s why we made the toughest portals possible. They’re built to get used and abused for miles without breaking down. Our cast and 6061 billet aluminum housings will plow through any obstacle. They come paired with our advanced steel backing plates that provide the best strength in the industry. If you want a lift you can count on, you want GDP.

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

GDP—The Most Trusted Name in Portals
More people ride on GDP portals than any other portal system. Why? We’ve got the quality, talent, and experience to make them better than anyone else. Our portals run the smoothest, last the longest, and come backed by the best customer service. If you want a portal gear kit for life, you want GDP.
