Gear Down and Go Big You like to get wild on your Polaris RZR 900, but are you getting as wild as you could. Take the reins off your ride with SuperATV’s 8” GDP Portal Gear Lift. With 8 inches of extra ground clearance and a torque-boosting 45% or 60% gear reduction, you can do what you think about doing but stop out of fear, and go places nobody else can.
GDP—the Most Trusted Name in Portals Going big isn’t risky. You’re following in the footsteps of thousands of riders that have chosen GDP before you. More riders roll on GDP portals than any other portal system. They’re out on the trail and parks every day, and with all that ride time, you can bet they’re the most trail-proven portals on the planet.
Perfect for Mud A big lift plus a 45% gear reduction equals one mud-munchin' monster. With clearance for huge tires and tons of torque to turn them, you’ll cruise over deeper mud and push through anything. Or take it over the top with a 60% gear reduction that lets you turn the biggest tires like stock. GDP and mud are a match made in heaven.
A Gear Reduction That Protects Your Drivetrain GDP puts the gear reduction in the hub instead of in the transmission. Because it comes after your drivetrain, it reduces stress on your axles, differential, prop shaft, and transmission. So even if you’re riding hard, you’re doing less damage than stock. That means that with GDP, you can keep the pedal down.

Unmatched Gear Material The gears in a portal gear lift are pretty important—that’s why ours are top-of-the-line. They’re made from precision-ground 9310 alloy steel so they mate perfectly each and every time. You get quiet portals that run smooth. It’s luxury and performance.
