Gen 3 Portals Are Geared for All
When we say our GDP portals are geared for all, we mean it. When you install SuperATV’s GDP 4” Portal Gear Lift on your Polaris Ranger 900, you’re getting more power and greater ground clearance in a package that’s customized to suit your riding style. First off, we let you pick the kind of housings you get—cast or billet aluminum. Then you get to choose your gear reduction, too. Looking to run bigger tires and get maximum torque? Go with a 30% gear reduction. In need of something to keep you smooth on the trails? Try our 15% gear reduction. Either way, you can’t go wrong.
GDP—the Most Trusted Name in Portals
No matter what you choose in terms of housings and gear reduction, you’ll be rolling on the best UTV portals in the world. Off-road enthusiasts choose GDP more than any other portal system on the market, and there’s a reason for that. Ours is the most tested, the most reliable, and the most proven.
Perfect for Mud
When you think of mud, you think of big tires and big lifts. GDP portals let you have both, allowing you to experience mud in a way like never before. They give you the torque needed to cut through bogs with ease, and the clearance needed to avoid getting swamped.
A Gear Reduction That Protects Your Drivetrain
A lot of vehicle modifications out there end up putting too much strain on your drivetrain. That’s why we love portals—they put the gear reduction right in the hub, which reduces the stress placed on your axles, differential, prop shaft, and transmission. You’ll be able to go hard and rest easy knowing that your machine’s most vital parts aren’t in danger.
Unmatched Gear Material
Our portals use the most premium, top-of-the-line gears you can find. We use a strong 9310 alloy steel that’s precision ground to ensure that they mate perfectly every time. These gears offer smooth and quiet performance, even when you’re riding your hardest.
Stronger Housings by Design
Trust us when we say we’ve done our research. We’ve seen what makes housings fail—you know, those designs and materials that give off a “what not to do” vibe. And we do the opposite of that. Our housings are stronger, smarter, and more dependable by design. Whether you go with a cast or our USA-made and CNC-machined 6061 billet aluminum, you’re getting portal housings that offer unmatched strength and reliability.
- 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 backing plates are just another feature that makes GDP portals the best. We make them using an advanced steel alloy that’s not your average metal. It’s specialized for ultra-high force applications and is even stronger than chromoly. Pair that with a thickness of 5/16” and you’ve got backing plates that will outlast your machine itself.
Advanced Gaskets and Seals
Whether you go with cast or billet, both housings use:
- Advanced Thermo-Tork® 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
You won’t get very far on bad bearings. Luckily, bad bearings aren’t an issue when you’re running GDP portals. We use roller bearings to hold our idler gear because there’s nothing stronger. We also utilize a double-angular contact bearing for the output bearing—it’s built to handle huge loads in all directions without showing premature wear. Long story short, these bearings are built to last.
Universal Hubs and Slotted Rotors
We use precision-ground, stainless slotted rotors because they stay cool and offer the braking power you need when you need it. As far as our universal hubs go, they just make your life easier. With 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs, you’re equipped to run just about any UTV wheel you can find. We also invented the tapered output shaft that our hubs attach to. It provides a more secure lock that won’t wobble or wear over time.
