Portal Gear Lift 4 Inch RZR Turbo – 30% Dual Idler High Lifter Kit
The Portal Gear Lift 4 Inch RZR Turbo by High Lifter is built for riders who demand maximum ground clearance, increased torque, and superior drivetrain protection. Designed for both 2-seat and 4-seat Polaris RZR Turbo models, this heavy-duty portal lift kit allows your UTV to handle deep mud, rocks, and extreme off-road terrain with confidence.
This system features a powerful 30% dual idler gear reduction that significantly improves torque while reducing stress on drivetrain components such as belts, axles, differentials, driveshafts, and gears. High Lifter improved the portal gearbox design by adding a second idler gear, allowing the load to be distributed across twice as many gear teeth. This design spreads the load over a larger surface area, reducing stress by nearly half and providing smoother, more reliable torque transfer.
The Portal Gear Lift 4 Inch RZR Turbo includes four forged portal gear boxes engineered for extreme durability. Forged aluminum housings are stronger than cast or billet aluminum used by many competitors, delivering long-lasting reliability even in the toughest riding environments.
