Unlock next level performance from your Polaris RZR XP 1000 with the SuperATV 4 Inch Portal Gear Lift. By lifting from the hubs instead of the suspension, this kit delivers serious ground clearance while keeping your suspension geometry right where it should be. Built in gear reduction eases drivetrain strain, making it the ideal upgrade for riders who push harder and run larger tires on tough terrain.
Engineered with precision ground billet steel gears and a reinforced dual idler design, these portals are made to stay cool, quiet and reliable under load. The added width improves stability in ruts and off camber sections, giving your RZR a planted, confident feel on every ride. It is a premium portal system designed to turn your machine into a true trail and mud weapon.
