SuperATV 4in. Portal Gear Lift for Polaris RZR Trail S 900

You don't ride on anyones terms but your own. So when it comes to equipping your Polaris RZR Trail S 900 to be more capable, you want options. SuperATV delivers with its GDP 4 Portal Gear Lift. If you want the toughest possible portals, upgrade to dual idler gears and ride harder than ever.

What Is a Dual Idler®?

Perfection takes time. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don't do a thing if they're not mated perfectly, though. Didn't think dual idlers mattered? With GDPs quality and experience, they finally do.

No Matter How You Ride, GDP Portals Are Built for It

Mud bogging is a whole different game with GDPs RZR Trail S 900 Portals and a 30% gear reduction. With all that torque, you can plow through mud with massive tires easier than ever. If you prefer riding flat out, you'll make great use of SuperATV 15% gear reduction. You still get plenty of torque, but its better suited for going fast on tires that aren't as huge.

GDP Stresses Your Drivetrain Less

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 O-rings with excellent oil resistance and low deterioration rates
