Polaris Ranger XP 900 8" Portal Gear Lift

Coming Soon


Polaris Ranger XP 900 & Ranger Crew XP 900 8" Portal Gear Lift 

The Portal Advantage 
Put an 8" Portal Gear Lift from SuperATV on your Ranger XP 900 and you’ll see how revolutionary it really is. With Portal Gear Lifts you get a massive lift and a gear reduction in one package. Reduce the stress on your axles while boosting your torque. Turn bigger tires with ease. Too good to be true? Not when it says Gear Driven Performance by SuperATV on the box. 

NEW to 8" Portals
Our 8" portals for the Ranger feature a 1.5" forward and rear offset. This gives you room for bigger tires—up to 34" without any other modifications.

The drive gear now seals internally against the housing, not the axle. Even if your axle is dirty, dinged up, or otherwise well-used, the drive gear still seals perfectly and keeps all contaminants out of your portal box.

To ensure the rest of the box is sealed, we utilize a new O-ring gasket in a machined groove that keeps oil in and mud out, no matter how deep you go.

45% Gear Reduction 
With a 45 percent gear reduction (1.82:1 ratio), you can do anything you want. That means freedom to run huge tires that still feel like stock. With Gear Driven Performance, you’re getting more than a gear ratio — you get freedom. Push your machine harder than you ever have before without breaking an axle or a prop shaft. Ride higher over any obstacle. Gear Driven Performance means freedom and fun.

Gear Driven Performance by SuperATV|Portal Gear Lifts

What Are Micro Polished Gears?
If you want maximum performance, choose our precision ground Micro Polished Gears. Micro polishing is a process that smooths out any imperfections (microscopic or otherwise) through a special acid wash and polishing treatment. The result is unbelievably smooth gears with less friction, better oil retention, and a longer lifetime than other gears. They will stay cool and quiet and even give you a little more power to the ground!

Do I need a Frame Stiffener?
Yes, we highly recommend running a SuperATV Frame Stiffener with your 8" Portal Gear Lift. Why? When you push the limits and go big with your Ranger 900, the stock frame just doesn't have what it takes. Drive too fast or 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.

If it is determined that repairs are required to your Gear Driven Performance portal, you MUST acquire an RGA number from our customer service team.
