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

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

The Polaris RZR XP Turbo 4″ Portal Gear Lift from High Lifter is designed to deliver increased ground clearance, improved torque, and enhanced drivetrain durability for serious off-road riders. Built specifically for Polaris RZR XP Turbo 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.

The advanced dual idler portal gear system improves traditional portal designs by incorporating a second idler gear inside the gearbox. This spreads the load across twice as many gear teeth, doubling the contact area and reducing internal stress by nearly half. The result is smoother torque transfer and reduced strain on belts, axles, differentials, driveshafts, and other drivetrain components when tackling challenging terrain.
