Gen 3 Portals are Geared for All
SuperATV's GDP 6" Portal Gear Lift for the Polaris RZR RS1 gives you a lift and a gear reduction in one package. Achieve the clearance to accommodate larger tires and the necessary torque to rotate them. The lift and gear reduction are situated in the hub to ensure the maintenance of suspension geometry while minimizing drivetrain stress. Personalize your experience by selecting either a 30% or 45% gear reduction, along with choosing between a cast or billet aluminum housing. GDP portals are truly designed for all types of off-road adventures. Discover what customer Goose Bellows has to say about our 6" portals on his renowned Can-Am Maverick XRS, aka Lil Buckin' Crazy.

45% – Perfect for Mud
Opt for the installation of large 6" portals with a 45% gear reduction to make way for huge tires and experience a significant increase in torque. This setup will allow the turning of oversized tires with ease and RV1 will effortlessly conquer the most challenging mud pits. These portals symbolize pure power and will demonstrate their mud-slinging capabilities.

45% – Perfect for Rocks
Choose a 6" portal box with a 45% gear reduction to access an abundance of torque for navigating over any size rock or boulder. With this level of power, rock shelves will feel like minor obstacles and boulders will be comparable to pebbles. The additional 6" of clearance enables the fitting of larger tires, reducing the frequency of needing to be winched out.

30% – Perfect for Everything
Select a 30% gear reduction to empower the turning of larger tires and to enhance versatility on numerous types of terrain. Whether it's mud, trails, hills, or high-speed roads, this setup is engineered to increase the UTV's performance across various terrains.
