4 Inch Portal Gear Lift Ranger XP 900 – High Lifter 30% Dual Idler Kit
The 4 inch Portal Gear Lift Ranger XP 900 by High Lifter is engineered for riders who demand more ground clearance, torque, and drivetrain protection from their Polaris Ranger. This heavy-duty portal lift system provides a massive performance upgrade for off-road riding, mud terrain, and oversized tire setups.
Featuring a powerful 30% dual idler gear reduction, this portal system distributes load across twice the gear teeth compared to traditional designs. The result is smoother power transfer, reduced drivetrain stress, and improved reliability when running larger tires or navigating extreme terrain.
The High Lifter 4 inch Portal Gear Lift Ranger XP 900 includes four forged portal gear boxes designed to outperform cast and billet aluminum competitors. Forging produces a stronger metal structure, delivering superior durability and longer service life in demanding off-road conditions.
