Polaris RZR PRO XP 4″ Portal Gear Lift – 15% Dual Idler (2 & 4 Seater)

Polaris RZR PRO XP 4″ Portal Gear Lift – 15% Dual Idler (2 & 4 Seater)

The Polaris RZR PRO XP 4″ Portal Gear Lift from High Lifter is designed to deliver superior ground clearance, increased torque, and unmatched drivetrain durability for serious off-road riders. Built specifically for Polaris RZR PRO XP models, this heavy-duty portal lift system raises your UTV by 4 inches while providing a 15% dual idler gear reduction that improves power delivery and overall off-road performance.

This advanced dual idler portal gear system enhances the traditional portal design by incorporating a second idler gear inside the gearbox. By distributing the load across twice as many gear teeth, the system doubles the contact area and significantly reduces internal stress. The result is smoother torque transfer and reduced wear on belts, axles, differentials, driveshafts, and other drivetrain components when tackling extreme terrain.

Performance Advantages

The Polaris RZR PRO XP 4″ Portal Gear Lift delivers more than additional ride height. The integrated gear reduction multiplies torque at the wheels, helping your RZR PRO XP maintain strong performance even when running oversized tires or navigating deep mud and rocky terrain.

The portal gear reduction also improves engine braking, reducing the need for frequent braking while descending steep terrain. This extends brake life while giving riders greater control in challenging off-road environments.
