Super ATV’s GDP 6” Portal Gear Lift for the Polaris RZR RS1 gives you more ground clearance and serious torque in one complete package.
By moving the lift and gear reduction to the hub, these portals let you run bigger tires while maintaining proper suspension geometry and reducing stress on your drivetrain. You can tailor the setup to your riding style with a 30% or 45% gear reduction and your choice of cast or billet aluminum housings. The 45% reduction is ideal for mud and rock riding, delivering massive torque to turn oversized tires and crawl over obstacles with ease. The 30% reduction offers the best all-around performance, balancing power, versatility, and top-end speed for trails, hills, and mixed terrain.
No matter which setup you choose, GDP portals are built for long-term durability. Precision-ground gears made from ultra-strong 9310 billet steel run cool, quiet, and smooth even under hard riding. The portal housings - available in cast or USA-made billet aluminum - are reinforced in key areas and engineered for proper oil flow and load distribution, with no unnecessary vents or gimmicks.
Advanced gaskets and seals provide complete oil coverage, helping prevent leaks and keeping your portals reliable ride after ride.
