Overhaul Your Ride with GDP Portals
GDP didn’t make the first side-by-side portal kit on the market—just the first kit that anybody gave a damn about. When you’re ready to unleash your ride’s true potential, there’s no better way to do it than with SuperATV’s GDP 6” Portal Gear Lift. Pick from a 30%, 45%, or 60% gear reduction and choose either dual idler or single idler gears. When we say we’re the industry leaders in portal gear lifts, we’re not messing around. Every piece of these portals was refined through a backbreaking process that involved lots of blood, sweat, and expertise.

Dual Idlers for Ultimate Strength
Perfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. They’re made with the industry’s toughest 9310 steel alloy. Two idler gears don’t do a thing if they’re not mated perfectly. Precision CNC grinding ensures that they do. Didn’t think dual idlers mattered? With GDP’s quality and experience, they finally do.

Dominate on Any Terrain
If you’re the kind of rider who’s constantly pushing limits and never backs down from a challenge, GDP portals were made from you. Whether you live for dunes, trail riding, or going nose-deep in mud, we’ve got the kit that will take your experience to a whole new level. Get a 30% gear reduction for faster rides that still pack plenty of torque. Go with a 45% reduction to run bigger tires and take on wilder terrain. Or build the most jaw-dropping mud machine around with a 60% gear reduction. You can even take your ride to the highest level with dual idler portals. These portals give you your torque back so you can ride with the best of them.

Less Strain on Your Most Vital Parts
Portals place the gear reduction right in the hub—that placement is a lifesaver for your drivetrain. Your axles, prop shaft, differential, and transmission won’t have to put in extra work just to keep up. That leaves you with smoother performance and longer-lasting components.

Made with Premium Parts
If you’re looking for the strongest and most trusted portal gear lift on the planet, you’ve found it. GDP portals are available with cast and billet aluminum housings, and they’re the thickest you can get. Combine that with 5/16” backing plates made from an advanced alloy steel and you’re left with portals that are absolutely unstoppable.

• Our housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Ultra-strong integrated rear hub backing plates—no more failure-prone aluminum hubs
• Enhance with Portal Blood—gear oil formulated for GDP Portals
• There are no gimmicks and no vents because vents do more harm than good—we know because we tested them

Advanced Gaskets, Seals, and Bearings
Our portals use:

• Advanced Thermo-Tork Gaskets and O-rings with excellent oil resistance and low deterioration rates
• A sealed input gear and double-lipped output seal
• 100% sealing coverage throughout so you can forget about oil leaks
• Double-angular contact output bearings to prevent premature wear
• Roller idler and drive bearings to maintain perfect gear meshing

Reinforce Your Ride with a Frame Stiffener
Major lifts and monster tires can take a toll on your ride's frame. Give yourself peace of mind by reinforcing your front end with a SuperATV Frame Stiffener. It’ll keep your frame from buckling under the pressure of extra weight and rough riding.
