Polaris Ranger Crew XP 900 4″ Portal Gear Lift – 15% Dual Idler
The Polaris Ranger Crew XP 900 4″ Portal Gear Lift from High Lifter is built to deliver increased ground clearance, improved torque, and enhanced drivetrain durability for demanding work and off-road adventures. Designed specifically for Polaris Ranger Crew XP 900 models, this heavy-duty portal lift system raises your UTV by 4 inches while providing a 15% dual idler gear reduction that improves wheel torque and overall performance.
The advanced dual idler portal gear system improves traditional portal designs by adding 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 on the drivetrain. The result is smoother torque transfer and reduced strain on belts, axles, differentials, and driveshafts when operating in rugged terrain or carrying heavy loads.
