4 Inch Portal Gear Lift Polaris Ranger 1000 – 30% Dual Idler High Lifter Kit
The 4 Inch Portal Gear Lift Polaris Ranger 1000 from High Lifter is engineered to deliver increased ground clearance, improved torque, and superior drivetrain durability for Polaris Ranger 1000 standard cab and crew models. This heavy-duty portal lift system is designed for riders who demand maximum off-road capability while running larger tires and tackling extreme terrain.
High Lifter enhanced the portal gearbox by adding a dual idler gear system. The second idler gear spreads the load across twice the number of gear teeth, increasing the contact area and reducing stress by nearly half. The result is smoother power transfer, improved reliability, and better torque delivery to the ground.
The 4 Inch Portal Gear Lift Polaris Ranger 1000 features a powerful 30% gear reduction, making it ideal for riders running large tires, including 40″ setups. This reduction improves low-end torque, reduces belt wear, and protects drivetrain components like axles, differentials, and driveshafts.
