Gen 3 Portals are Geared for All
SuperATV's GDP 4" Portal Gear Lift is Geared for All. Choose from 15% or 30% gear reductions and cast or billet aluminum housings so you can optimize for the riding style you prefer.

Perfect for Mud
If you move up to a 30% gear reduction, you'll be ready to take on bigger, sloppier mud holes. A 30% gear reduction with 4" portals gives you a big boost in torque so you can run huge tires through thicker slop and get all your UTV's power to the ground. When you're done with the mud, a 30% gear reduction can get you through trails and rocks just as easily.

Perfect for Rocks
Put 4" portals and a 30% gear reduction on your machine and get the torque you need crawl over rocks like they're not even there. You'll have the clearance to get over anything without scratching up your skid plate, and you'll have room to run bigger tires. These portals are built for boulders.

Perfect for Dunes
Put 4" portals and a 15% gear reduction on your machine and see how fast you can go. You'll fly up dunes like they're flat ground and keep your speed up for those wide-open valleys. With all that extra torque, the dunes will feel more intense than ever.

Perfect for Trails
Get 4" portals and a 15% gear reduction on your machine and take on the path less traveled. You'll fly through the trail and clear those technical hills or washouts easily thanks to that extra torque. It'll show you what your UTV can really do.

Better Gears
Our gears are precision ground and made with 9310 billet steel alloy for high strength and high speed. That means they're cool and quiet even when you're hammering down the throttle on the road, and they have strength to withstand every ride.

Stronger Housings by Design
Try as you might, you won't find housings stronger than what we use on our GDP portals. Our housings are smarter, stronger, and more reliable by design. So whether you choose cast or USA-made and CNC-machined 6061 billet aluminum, you're getting housings that offer unmatched strength and dependability. We've got the experience and the riders on the trail to back it up.

• 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

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
