GDP—the Most Trusted Name in Portals
More riders roll on GDP Portals than any other portal system. That’s because we’ve made and sold thousands of kits, and they’re out on the trail every weekend. Next time you’re at the ride park, take a look around—your certain to see more than a few trail-proven GDP Portals.
A Gear Reduction That Protects Your Drivetrain
A portal gear reduction reduces the stress on your axles, differential, prop shaft, and transmission unlike a traditional transmission gear reduction. That’s because the reduction comes after your drivetrain and not before. That means you can keep the pedal down and do less damage than stock.
Learn more about how tire size and gear reduction can unleash your machine’s potential.
Unmatched Gear Material
Our top-of-the-line gears use premium, precision-ground 9310 alloy steel to make sure they mate perfectly, run smooth, and won’t break. That means they’re the quietest and most durable portals you can get, even when you push them hard.
Stronger Housings by Design
We make our portal housings as strong as possible because we know how to design them, manufacture them, and assemble them to be strong. They’re strength comes from experience that you can’t fake. So whether you choose cast aluminum or USA-made billet aluminum, you’re getting a housing that can’t be beat.
- 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
We make your backing plates with a premium steel alloy that’s stronger than chromoly and built for incredibly high-force applications. At 5/16” thick, these plates are tough enough to hold your suspension and portals together no matter how you ride.
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
- Rubber O-rings that completely seal the housings
- A sealed input gear and double-lipped output seal
- 100% sealing coverage throughout so you can forget about oil leaks
Bearings That Rock
The smallest details on GDP are built to be bulletproof because we know from experience that you can’t cut corners anywhere. That’s why our output bearing is a double-angular contact bearing that will survive heavy hits and big bumps and keep your wheels riding true.
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. With all the most popular bolt patterns built in to every hub, you can use wheels from almost any source. 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 Stiffener
Even though the RZR PRO XP is one of the toughest and strongest machines Polaris has ever built, it doesn’t mean its frame can handle the heavy-duty awesomeness of 8” GDP Portals. That’s why we highly recommend a frame stiffener. We’ve ridden hard enough to know that it happens, and that you don’t want it to happen. Get a frame stiffener and don’t worry about it.
