Gen 3 Portals Are Built for All
There’s nothing better than customizing your machine to suit your ride style. When you add SuperATV’s GDP 6” Portal Gear Lift to your Kawasaki Teryx S, that’s exactly what you’re doing. Our portals give you a boost in ground clearance, room for bigger tires, and your choice of a 30% or 45% gear reduction. You also get a say in whether we use cast or USA-made billet aluminum housings, both of which offer unbeatable strength. No matter which options you go with, GDP offers exactly what you need.
GDP—The Most Trusted Name in Portals
Still not sure whether SuperATV’s portals are right for you? Just ask any of the thousands of riders who are already rolling on GDP. We’ve invested more time and money in portals than anyone else in the industry. And as soon as you get these things on your Teryx, you’ll see that our efforts paid off.
Perfect for Mud
Mud and portals go hand in hand—they’re a match made in heaven, if you will. You’ll need the extra 6” of lift to cut through those deep, swampy mud pits without getting stuck. And without a gear reduction, you may not have the torque you need to keep your wheels spinning. If you thought mud was fun before, just wait until you try it with these Teryx S 6” portals.
A Gear Reduction That Protects Your Drivetrain
Some modifications place the gear reduction in your drivetrain which places unnecessary stress on your axles, prop shaft, and transmission. Luckily, GDP Portals don’t fall into that category. We place the gear reduction directly in the hub to greatly reduce the amount of strain placed on your Teryx’s most vital parts. You’ll get more life out of your drivetrain, and you’ll save money and hassle in the long run.

The Best Gear Material Around
The best portals are made of the best gear material. That’s why we use premium, top-of-the-line 9310 alloy steel gears to keep your portal gear lift running flawlessly. Our gears are precision ground for quiet operation and perfect mating every time. As a result, you’re left with a comfortable and smooth ride every time you get behind the wheel.
Our Housings Are Stronger by Design
The portal housings keep everything safe, protected, and in its place. That’s why we spared no expense when designing GDP Portal housings. After years of research and testing, we’re able to give you two unbeatable options. Choose from cast and USA-made 6061 billet aluminum with a sleek CNC-machined finish. Spoiler alert: you can’t go wrong. Either way, you’re getting the best portal boxes on the market.
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
We didn’t stop at strong housings—our backing plates are just as impressive. They’re 5/16” thick and made with an advanced steel alloy. This isn’t your average alloy—it’s even stronger than chromoly and specialized for ridiculously high-force applications. The backing plates on GDP Portals will outlast your machine’s lifespan by a longshot, so you’ll never have to worry about taking it easy for fear of breaking something.
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
- You Won’t Find Better Bearings
If your bearings fail, your portals are toast. That’s why we didn’t cut any corners with this part either. We use roller bearings to hold the idler gear in place. Our output bearing is a double-angular contact bearing that can handle huge loads in any direction without showing premature wear. We’re not just blowing steam when we say our bearings are the best—they’re truly built for battle and just another reason why GDP is the best.
Universal Hubs and Slotted Rotors
Our portals use precision-ground, stainless steel slotted rotors to run cool and deliver the precise braking power you need. They come with 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs so you can run just about any side-by-side wheel imaginable. We also invented the tapered output shaft that the hubs attach to, which gives you a more secure lock that won’t wobble or wear over time.
