Gen 3 Portals are Geared for All

SuperATV’s GDP 4” Portal Gear Lift for the Polaris RZR XP 900 is Geared for All. What do we mean by that? Our 4” portal lift is available with 15% or 30% gear reductions. You can get exactly what you want for your riding style and preferred riding environment.

Perfect for Mud

Get a 30% gear reduction and start flingin’ mud. With a massive boost to torque, you can turn bigger tires that chew through the thickest bounty holes. When you gear down and go big, your machine will turn into a mud monster. Plus, with a 30% gear reduction you can still use it on the road and tear up trails and rocks.

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 Trails

Get 4” portals and a 15% gear reduction on your Polaris RZR 900 and take on the trail less traveled. You’ll keep that high speed and leave your friends in the dust when you hit a hill or dirt shelf. It’ll bring out your UTV’s true power.

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
