A Big Lift with Big Power Your Kawasaki Teryx KRX 1000 isn’t supposed to be an average UTV. Install an 8” GDP Portal Gear Lift and it will be anything but. It gives you awesome ground clearance, boosts power with a 45% gear reduction, and makes you a beast everywhere you roll. You’ll dominate monster mud holes and crazy rock gardens like they’re not even there.
GDP—the Most Trusted Name in Portals When it comes to game-changing performance, you shouldn’t settle for anything less than GDP. Why? GDP portals are tried and true. From the unmatched portal engineering experience to the thousands of riders that swear by them every day, our portals are unmatched. In fact, more riders roll on GDP portals than any other portal system. If you want a name you can trust, you want Gear Drive Performance.
Master of Mud If you want to dominate deep mud holes that swallow other riders whole, there’s only one way to do it. With 8 inches of extra ground clearance, you won’t get in over your head. But what really makes it tick is the 45% gear reduction built into the hubs. You get tons of torque to turn big tires through the deepest, nastiest mud you can find. A set of portals will turn you into the master of mud.
A Gear Reduction Protects Your Drivetrain When the gear reduction is in the hub instead of the transmission, your entire drivetrain benefits from it. Your axles, differential, prop shafts, and transmission will face less wear and tear thanks to this gear reduction.

Unmatched Gear Material We use top-of-the-line gears so that you get a bulletproof portal hub. They’re made with 9310 alloy steel which is one of the strongest gear materials out there. They’re precision ground so that they mate perfectly all the time. These portals run smooth and quiet even when the pedal’s down.
Stronger Housings by Design Whether you choose cast or billet aluminum for your housing, you know you’re getting a housing that’s built for battle. We’ve spent years refining our housing design to maximize strength in key areas that see the most force. With more than ten thousand housings out on the trail, you can count on them standing up to the worst.
- 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 The advanced steel alloy we use in the portal backing plates is as strong as it gets. Anything less would buckle under the intense leverage where the box meets the suspension. At 5/16” thick, our plates will hold you together no matter what.
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 A portal’s output shaft takes a huge amount of abuse, but it’s really the bearing that takes the brunt. That’s why we use a double-angular contact bearing. It's built to take huge shock loads from any direction without failing or wearing prematurely. Without it, your portals would fall apart in no time. We’ve made sure every detail can take the heat.
Universal Hubs and Slotted Rotors Our precision-ground, stainless steel slotted rotors stay cool to give you the braking power you need when you need it. They come with 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs so you can fit wheels built for almost any side-by-side. We invented the tapered output shaft that our hubs attach to, which provides a more secure lock that won’t wobble or wear over time.
Reinforce Your UTV with a Frame Stiffer These 8” portals are hardcore. In fact, they’re more hardcore than your Kawasaki KRX. You need a heavy-duty frame stiffener to make sure that your UTV survives all the action packed rides you’re about to go on. Trust us, we’ve bent more frames than we can count. Don’t mess around. Get a frame stiffener.
