SuperATV Polaris Sportsman XP 4" Portal Gear Lift

Gen 3 Portals Are Geared for All
Off-roading isn’t a “one size fits all” thing. Your riding style is as unique as you are, and we designed our portals to reflect that. When you buy SuperATV’s GDP 4” Portal Gear Lift for your Polaris Sportsman XP, you have a say in what kind of housings we use (cast or billet aluminum) and the amount of gear reduction you get. Are you all about maximum power? Go with a 30% gear reduction. Is trail riding more your thing? Try our 15% gear reduction. Whatever your style, one thing stays the same—GDP portals will totally change the way you look at riding.

GDP—the Most Trusted Name in Portals
Don’t just take our word for it when we tell you GDP portals are the best in the business. Look at the thousands of riders across the country who put them to the test day after day! There’s a reason why more riders choose GDP portals over any other system—they’re long tested, trail proven, and highly trusted. Why would you buy portals from anyone else?

Perfect for Mud
Mud riding takes on a whole new meaning when you have GDP portals installed on your quad. You’ll be tearing through the thickest bogs and making it look easy! The torque boost gives you extra power to dominate in the mud, and the ground clearance keeps you from getting swamped. Sounds like a recipe for fun if we’ve ever heard one.

A Gear Reduction That Protects Your Drivetrain
Portal gear lifts place the gear reduction in your hub, which greatly reduces the amount of stress placed on your vehicle’s most critical components. This means you can relax and go hard knowing that your axles, differential, prop shaft, and transmission aren’t being abused. Your driveshaft will thank us.

Unmatched Gear Material
We use nothing but the best when it comes to GDP portals, and our gears are no exception. They’re made of a strong 9310 alloy steel and precision ground to ensure that the teeth match up perfectly with every revolution. Our gears deliver a smooth and quiet performance ride after ride.

Stronger Housings by Design
No portals in the world have housings stronger than what you’ll find on GDP portal gear lifts. We’ve put in years of research and testing to bring you housings that are strong enough to keep up with even the most rugged off-road lifestyle. So whether you go with cast or our USA-made 6061 billet aluminum with a sleek CNC-machined finish, just know you’re getting portal housings that truly are second to none.

• Our housings are reinforced in all the right places
• They’re built with better oil flow and gearing forces in mind
• There are no gimmicks and no vents because vents do more harm than good—we know because we tested them

The Strongest Portal Backing Plates You Can Get
Our extra-strong backing plates are just another reason why GDP portals are the best around. They’re made out of an advanced steel alloy, and trust us when we say this isn’t just any old metal. It’s specialized for ultra-high force applications and is even stronger than chromoly. And at 5/16” thick, you can bet these plates aren’t going to fail you anytime soon—or ever.

Advanced Gaskets and Seals
Whether you go with cast or billet, both housings use:

• Advanced gaskets with excellent oil resistance and a lower deterioration rate than Kevlar gaskets
• A sealed input gear and double-lipped output seal
• 100% sealing coverage throughout so you can forget about oil leaks

Bearings That Rock
The performance of a portal gear lift depends on the quality of the bearings inside. That’s why we didn’t cut any corners when designing ours. We use roller bearings to hold our idler gear in place, because there’s no such thing as compromising when it comes to strength. And our output bearing is a double-angular contact bearing—that means it can handle huge loads in any direction without wearing down prematurely. With bearings this good, you know your GDP portals are built to last.

Universal Hubs and Slotted Rotors
Our precision-ground, stainless steel slotted rotors keep their cool no matter how wild you get. They’re designed to give you the braking power you need, as soon as you need it. We also include universal hubs, just to make things easier on you. With 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs, you’re free to run just about any size ATV wheel you can find. We also invented the tapered output shaft that our hubs attach to. It gives you a more secure lock that won’t wobble or wear over time.
