Super ATV’s 4” GDP Portal Gear Lift for the Polaris RZR XP 1000 isn’t just another portal kit - it’s the first one that truly delivers power, performance, and reliability.
Offering 15% or 30% gear reduction options, it boosts both ground clearance and torque, letting you conquer bigger obstacles with confidence. Dual Idlers are included to spread the load across the gears, giving you the strongest and most dependable gear setup on the market. With GDP, you get precision-engineered portals that let your RZR perform at its peak, whether you’re tackling trails, mud, or monster tires.
The Dual Idler system is a game-changer, using a second idler gear to transfer torque over twice the surface area, while precision CNC grinding ensures perfect gear mating. Made from tough 9310 steel alloy, the gears deliver maximum strength and durability. Gear reduction in the hub reduces stress on axles, driveshafts, differentials, and transmissions, helping your drivetrain last longer. The kit’s cast and billet aluminum housings are reinforced for gear retention and optimized for oil flow, paired with advanced steel backing plates and Portal Blood gear oil for unmatched durability.
GDP portals also feature advanced gaskets, O-rings, double-lipped seals, and high-quality bearings to prevent leaks and premature wear. For extra stability when running bigger tires and extra ground clearance, a Super ATV Frame Stiffener is recommended. And if you need guidance, GDP’s top-rated portal tech support is ready to help you get the perfect setup for your RZR.
This isn’t just a lift - it’s a complete upgrade that makes your RZR stronger, more capable, and ready for anything.
