High Lifter 4″ Portal Gear Lift RZR XP 1000 (2 and 4 Seater) – 30% Dual Idler

High Lifter 4″ Portal Gear Lift RZR XP – 30% Dual Idler Portal Kit

The High Lifter 4″ Portal Gear Lift RZR XP is engineered for riders who demand maximum ground clearance, increased torque, and superior drivetrain protection. Designed for both 2-seat and 4-seat Polaris RZR XP 1000 models, this heavy-duty portal lift system transforms your UTV into a high-performance off-road machine capable of tackling mud, rocks, and extreme trail conditions.

This portal lift kit features a powerful 30% dual idler gear reduction that significantly improves torque while reducing strain on belts, axles, differentials, and driveshafts. By adding a second idler gear inside the gearbox, the load is distributed across twice as many gear teeth, reducing stress and providing smoother and more reliable torque transfer.

The High Lifter 4″ Portal Gear Lift RZR XP includes four forged portal gear boxes designed for extreme durability. Forged aluminum housings are stronger than both cast and billet aluminum used by many competitors, ensuring long-lasting reliability even in the harshest off-road environments.
