Gen 3 Portals are Geared for All
SuperATV’s GDP 4” Portal Gear Lift for the Arctic Cat HDX is Geared for All. Choose from 15% or 30% gear reductions and cast or billet aluminum housings so you can optimize to fit your style.
Perfect for Mud
Move up to a 30% gear reduction to turn you HDX into a mudding party wagon. That boost in torque means your tires keep turning through the thickest peanut butter mud. With 4” of lift, you have room for bigger tires which means more grip and more rip. When you’re done with the mud, a 30% gear reduction can get you through rocks, trails, and roads 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 the Trails
Get 4” portals and a 15% gear reduction on your machine and take on the trail less traveled. Ditches, shelves, and creek crossings are no big deal for your boosted torque, and you can still fly when the trail is easy.
Perfect for Work
With 4” portals and a 15% gear reduction on your HDX, you’ll have clearance to get over the ditches and debris around your property and you’ll have the gear reduction to push through ruts and ditches easily all while towing a trailer full of tools. Plus, you’ll still have enough speed to cruise down the road.

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
We dare you to find housings stronger than what we make for our GDP portals. Just like everything else that goes into this product, our housings are well researched and long tested. And you get a choice—go with cast or USA-made, CNC-machined 6061 billet aluminum. Regardless of what you pick, you’re getting portal housings with strength and reliability that is unmatched.
- 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 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
