4″ Portal Gear Lift Ranger Crew XP 900 – High Lifter 30% Dual Idler Kit
The 4″ Portal Gear Lift Ranger Crew XP 900 by High Lifter is built for riders who need more ground clearance, improved torque, and maximum drivetrain protection. Designed specifically for Polaris Ranger Crew models, this heavy-duty portal lift system delivers exceptional off-road capability for mud riding, trail adventures, and oversized tire setups.
This kit features a powerful 30% dual idler gear reduction that significantly improves torque delivery 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 power transfer.
The High Lifter 4″ Portal Gear Lift Ranger Crew XP 900 includes four forged portal gear boxes engineered for extreme durability. Forged aluminum construction creates stronger housings compared to cast or billet designs, ensuring long-lasting reliability in demanding off-road conditions.
