Take Your Polaris RZR XP to the Next Level
Transform your off-road experience with the SuperATV 4” GDP Portal Gear Lift, the ultimate upgrade for your Polaris RZR XP. This advanced portal system is engineered to deliver unmatched performance, strength, and reliability on every terrain. Choose between a 15% or 30% gear reduction to tailor your ride to your specific needs—whether you crave high-speed desert runs or torque-packed rock crawling. Designed with precision and durability in mind, this system enhances ground clearance, reduces drivetrain wear, and maximizes power transfer for the toughest rides.
Dual Idler Gear Innovation
SuperATV’s dual idler gear design sets the standard for durability and performance. By integrating a second idler gear inside the portal box, the load is spread evenly across more surface area, ensuring consistent torque distribution and superior strength. Each gear is crafted from 9310 alloy steel and precision CNC ground for perfect mating and quiet operation. The result is a smoother, stronger, and more efficient portal system built to withstand extreme riding conditions.
Built for Every Terrain
Whether you’re tackling deep mud, rocky trails, or sandy dunes, the GDP Portal Gear Lift lets you ride your way. A 30% reduction provides the torque needed for oversized tires and heavy-duty crawling, while a 15% reduction offers the ideal balance for high-speed adventure. No matter the challenge, GDP portals deliver consistent performance and reliability that off-road enthusiasts trust.
Unmatched Strength and Protection
Every component of the GDP Portal Gear Lift is engineered for resilience. Choose from cast or 6061 billet aluminum housings reinforced for superior gear retention and optimized oil flow. The advanced steel alloy backing plates outperform chromoly for incredible durability. To ensure maximum sealing and protection, each portal includes advanced gaskets, O-rings, and double-lipped seals that eliminate oil leaks and contamination. Double-angular contact output bearings and roller idler bearings maintain flawless gear alignment and longevity.
Reduced Drivetrain Stress
This system places the gear reduction directly in the hub, significantly decreasing strain on your axles, differential, prop shaft, and transmission. The result is a smoother, more efficient drivetrain that lasts longer and performs better under load.
