  Gen 3 Portals Are Geared for All
  Take a second and imagine what it would be like to ride 8” higher and with a whole lot more power. Sounds like fun, huh? With this GDP Portal Gear Lift on your Polaris RZR Trail S 900, that imagination becomes reality. These portals give you the incredible clearance and unbeatable torque you need to tackle any terrain. They also give you options—choose between cast or billet aluminum housings and a 45% or 60% gear reduction. What are you waiting for? GDP is ready and waiting to transform your ride.
  
  GDP—the Most Trusted Name in Portals
  Not sure if GDP is right for you? We think it is, but why don’t you ask one of the thousands of riders already using portals every week? More riders roll on GDP portals than any other portal system. That means we’ve got experience that no one else has. When it comes to reliability, quality, and performance, nothing’s as trail-proven as GDP.
  
  Perfect for Mud
  It seems like we see more RZRs in the mud every time we go out—it’s a great side-by-side for it. But with 8” portals and a 45% or huge 60% gear reduction, it becomes the ultimate mud UTV. You’ll have room for bigger tires and all that torque means you can push through anything, if the mud’s even deep enough to reach your skid plate.
  
  A Gear Reduction That Protects Your Drivetrain
  Portals put the gear reduction right in the hub. That matters because putting it after your drivetrain components will make them last longer. GDP reduces the stress on your axles, differential, prop shaft, and transmission even if you’re rolling on huge tires.
   
  Unmatched Gear Material
  What’s more important than gears in a portal gear lift? Nothing. That’s why our top-of-the-line gears are made from precision-ground 9310 alloy steel. They mate perfectly every time and give you smooth, quiet portals no matter how fast you go. GDP gives you luxury-grade performance.
  
  Stronger Housings by Design
  Some might think you can use brute force to make a better housing. They’d be wrong. We use precise design honed over years and backed by hundreds of thousands of ride hours to make the strongest portal boxes in the industry. So whether you want cast or USA-made billet aluminum for your housings, you know your getting high-quality, precision hardware that will stand up to any ride.
   

·  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
The Strongest Portal Backing Plates You Can Get
How do we make the strongest backing plates on the planet? We start with an advanced steel alloy that’s even stronger pound-for-pound than chromoly. Then, we make it 5/16 inches thick, and, finally, we hand-weld gussets and pivot blocks to it. We went all out on strength because if you’re backing plate doesn’t hold up, you’re done playing. So keep playing with GDP.

Advanced Gaskets and Seals
Whether you go with cast or billet, both housings use:
 

·  Advanced Thermo-Tork® gaskets to keep oil in and water out. They have excellent oil resistance and a lower deterioration rate than Kevlar gaskets.

·  A sealed input gear and double-lipped output seal.

·  100% sealing coverage throughout. You can forget about oil leaks—nothing’s getting in or out, ever.
Bearings That Rock
All the strongest housings, gears, plates, and hardware would mean nothing if we had just average bearings. But, like everything else, we opted to make them as good as possible. With a double-angular contact bearing on the output shaft that can take hit after hit, you can rest easy knowing that even GDP’s bearings are built for battle.

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 so you can use wheels from just about any side-by-side. 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.

Frame Stiffener Required
These 8” portals are big, beefy, and powerful. In fact, they give you such a big lift that your RZR needs a frame stiffener to keep from bending its chassis. We’ve put it through its paces and bent plenty of frames. Trust us and get a frame stiffener.
