Polaris RZR XP Turbo S 8 Inch Portal Gear Lift

Gear Down and Go Big
What can you do with a monster 8” GDP Portal Gear Lift and a 45% gear reduction? Anything you want. With room for up to 40” tires and the boosted torque to turn them, your Polaris RZR XP Turbo S will push through deeper mud and climb over bigger rocks. With GDP, the way forward is to drive straight through.

GDP—the Most Trusted Name in Portals
Why should you choose GDP over others? Because the verdict has been delivered, and thousands of riders choose GDP to carry their ride every weekend. In fact, more riders roll on GDP Portals than any other portal system. You’re not taking a chance on unproven technology, you’re choosing the most trusted name in portals.

Perfect for Mud
Bounty holes aren’t built for stock machines, and they favor those that go big. With 8 inches of ground clearance on top of whatever monster mud grips you get, you’ll be anything but stock. With GDP, you won’t be neck deep, and that extra power to the ground® will keep your tires turning and your machine moving forward.

A Gear Reduction That Protects Your Drivetrain
The gear reduction on GDP portals comes at the very end of the drivetrain. Since it’s right in the hub, that means your axles, differential, prop shaft, and transmission all benefit from it. You get less stress on your components and machine that lasts longer than stock.

Better Gear Material
We take Gear Driven Performance seriously, that’s why we don’t skimp on gear material. They’re made from precision-ground 9310 alloy steel that make them quiet and smooth. These top-of-the-line gears are built for the way you ride.

Stronger Housings by Design
You can choose from either cast or our USA-made billet aluminum. No matter what you choose, you know you’re getting the strongest designed portal housing on the planet. With tens of thousands out getting beat on every week, you know these housings are trail proven.

• 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
We use an advanced steel alloy for our backing plates that’s unmatched in strength and durability. It’s stronger than chromoly and at 5/16” thick, it’s strong enough to hold your suspension together for the lifetime of your side-by-side.

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

Bearings That Rock
We know that even the smallest details are important. That’s why our output bearings are the best you can get. They’re double-angular contact bearings so they don’t break or wear prematurely when you’re hitting bumps and riding hard. It’s one more way we make sure GDP is the best.

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 almost any side-by-side wheel on these portals. We made them that way to make your life easier. We invented the tapered output shaft that our hubs attach to. It provides a more secure lock that won’t wobble or wear over time.

Reinforce Your UTV with a Frame Stiffener
We highly recommend running a SuperATV Frame Stiffener with your 8" Portal Gear Lift. Your stock RZR Turbo S frame is tough, but it’s not tough enough to handle going this big. Get a frame stiffener and get piece of mind that your machine will hold together when the pedal’s down.
