Gear Down and Go Big 
SuperATV’s GDP 8” Portal Gear Lift for the Polaris RZR 900 is geared down so you can go big. It gives you a lift and a 45% gear reduction in one box. Get the clearance to run bigger tires and the torque you need to turn them. The lift and gear reduction are in the hub, so they maintain suspension geometry and reduce drivetrain stress. With huge clearance, huge torque, and optional billet aluminum housings, you can install monster tires and ride high through anything.  

Perfect for Mud 
With 8” portals and a 45% gear reduction, you get clearance for huge tires and a massive boost in torque. It’ll turn monster tires like they’re stock. Your 900 will be the most powerful mud flinging machine in the park. Now you just need to find a bounty hole deep enough for you. 

Perfect for Rocks 
Get tons of torque to crawl over any rock or boulder you can find by installing an 8” portal box with a 45% gear reduction. With that much power, there’s no boulder too big or crawl too technical. With 8” of clearance, you can run any tire size you want and take on the most technical rock crawling trails you can find. 

Learn more about how tire size and gear reduction can unleash your machine’s potential. 

Better Gears 
Our gears are precision ground and made with 9310 billet steel alloy. They’re designed to take all the torque and abuse you can give them without chipping teeth or blowing up. Our precise design and manufacturing mean they’re cool and quiet even when you’re hammering down the throttle in the mud hole.  

   Billet Housings 
Choose billet or cast aluminum housings to finish your portals. Our billet housings are CNC machined right here in Madison, Indiana and give you increased strength and consistency over cast. Plus, they look good painted with mud. 

Reinforce Your UTV with a Frame Stiffener 
We highly recommend running a SuperATV Frame Stiffener with your 8" Portal Gear Lift. The stock frame just doesn't have what it takes. Bump too hard and the OEM frame will bend. Trust us — we've done it. A frame stiffener reinforces your frame enough to let you ride your 8" portals with monster tires and no worries.
