Upgrade your Polaris RZR S 1000 with an 8 GDP Portal Gear Lift from Super ATV for unmatched ground clearance and torque with your choice of a 45% or 60% gear reduction.
Perfect for mud, rocks, and extreme terrain, GDP portals are the most trusted name in the industry - proven by thousands of riders.
The gear reduction is placed in the hub (not the transmission), reducing stress on your drivetrain. Built with 9310 alloy steel gears, reinforced billet or cast aluminum housings, and 5/16 thick advanced steel backing plates, these portals are engineered for extreme durability.
Advanced seals prevent leaks, and double-angular contact bearings ensure reliability under harsh impacts. Includes universal hubs with multiple bolt patterns and slotted rotors for excellent braking.
A frame stiffener is recommended to support the added lift and torque.
