Polaris RZR XP 1000 4″ Portal Gear Lift – 15% Dual Idler (2 & 4 Seater)

Polaris RZR XP 1000 4″ Portal Gear Lift – 15% Dual Idler (2 & 4 Seater)

The Polaris RZR XP 1000 4″ Portal Gear Lift from High Lifter is engineered to deliver superior ground clearance, increased torque, and enhanced drivetrain durability for serious off-road riders. Designed to fit both 2-seater and 4-seater Polaris RZR XP 1000 models, this heavy-duty portal lift 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 improves traditional portal designs by adding a second idler gear inside the gearbox. By spreading the load across twice as many gear teeth, the system doubles the contact area and reduces internal stress by nearly half. The result is smoother torque transfer and less strain on belts, axles, differentials, driveshafts, and other drivetrain components when tackling extreme terrain.

• CNC Precision Machined Gears – Heat-treated alloy steel gears ensure durability and quiet operation.

Performance Advantages

The Polaris RZR XP 1000 4″ Portal Gear Lift offers more than additional ride height. The integrated gear reduction multiplies torque at the wheels, allowing your RZR XP 1000 to maintain strong performance even when running oversized tires or navigating deep mud and rocky terrain.

The portal gear reduction also improves engine braking, helping reduce the need for frequent braking when descending steep trails. This extends brake life and provides better control during aggressive off-road riding.
