Polaris RZR Trail 900 4" Portal Gear Lift

Gen 3 Portals Are Geared for All
When it comes to side-by-sides, one size does not fit all riders. Your machine should be as unique as you are, and we kept that in mind when designing this GDP 4" Portal Gear Lift. It adds both a lift and a gear reduction to your Polaris RZR Trail 900! You get to choose how much of a reduction you get (15 or 30%) and your preferred style of housings (cast or billet aluminum). No matter what options you go with, one thing's for sure your ride will never be the same.

GDP the Most Trusted Name in Portals
More riders turn to SuperATV for their portal needs than anyone else in the industry. That's because we know our stuff. We've invested more time and money in designing portal gear lifts than any other manufacturer in the industry. Thanks to industry-leading technology and countless hours of field and lab testing, we're able to deliver exactly what you need to take your ride to the next level.

Perfect for Mud
Some things are just made to go hand in hand peanut butter and jelly, biscuits and gravy, and portals and mud, to name a few. You haven't experienced mud in your side-by-side until you've done it on a portal gear lift. The 4" lift keeps you from getting swamped and gives you room for bigger tires, and the torque boost makes cutting through thick mud a piece of cake.

A Gear Reduction That Protects Your Drivetrain
Portal gear lifts put the gear reduction directly in the hub, which is good news for your drivetrain. This placement greatly reduces the amount of stress placed on your axles, differential, prop shaft, and transmission. Because portals don't make those parts work overtime, they'll last longer which saves you money in the long run. You're welcome.


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

• Advanced 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
Our bearings keep your portal gear lift running smoothly through all conditions. Incredibly strong roller bearings hold the idler gear in place, absorbing all that internal pressure. And because the output bearing takes the most force, we utilize a double-angular contact bearing. All in all, these bearings are designed to keep your portals running for miles without fail.

Universal Hubs and Slotted Rotors
All GDP portals utilize precision-ground, stainless steel slotted rotors. They're designed to stay cool and deliver the braking power you need, exactly when you need it. Our universal hubs come with 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs, allowing you to run just about any side-by-side wheel under the sun. We also invented the tapered output shaft that attaches to our hubs. It gives you a more secure lock that won't start to wobble over time.
