High Lifter 6 Inch Portal Gear Lift 60% Dual Idler for Polaris RZR RS1 (2018–2022)

High Lifter 6 Inch Portal Gear Lift 60% Dual Idler for Polaris RZR RS1 (2018–2022)

Transform your single-seat machine with the High Lifter 6 Inch Portal Gear Lift 60% Dual Idler for Polaris RZR RS1. Engineered specifically for the Polaris RZR RS1 platform, this heavy-duty RS1 portal gear reduction kit delivers extreme torque multiplication, increased ground clearance, and unmatched drivetrain protection.

The aggressive 60% gear reduction is ideal for riders running 40 inch tires or larger, restoring lost torque while reducing stress on belts, axles, differentials, driveshafts, and transmission components.

60% Gear Reduction with Dual Idler Technology

High Lifter enhanced the portal box design by integrating a second idler gear inside the gearbox. This dual idler portal system spreads load across twice as many gear teeth, doubling surface contact and cutting stress in half.

The result is more reliable torque transfer, smoother power delivery, and longer gear life under aggressive riding conditions.

The 60% gearing also dramatically improves engine braking performance, reducing brake wear and giving you better control in steep or technical terrain.

Forged Aluminum Portal Gear Boxes

Unlike competitors that use cast or billet housings, High Lifter utilizes forged aluminum portal gear boxes. Forging creates a tougher, stronger housing capable of handling extreme mud riding and high-torque applications.

Advanced Sealing & Heavy-Duty Construction

• High-density Kevlar fiber gaskets resistant to oil and coolant
• No additional sealant required
• Dual oil seals on spindle shaft for increased sealing area
• True triple-sealed input shaft with protective wiper seal
• Massive 5/16″ steel backing plates with bent flanges
• Welded gusset brackets for maximum strength
• 13” precision ground stainless steel slotted rotors

Precision Heat-Treated Gears

Alloy steel gears undergo a specialized heat-treatment process to increase both internal and external strength. CNC precision ground machining ensures proper fitment, while controlled gear lapping provides smoother, quieter operation.

Vehicle Fitment

This Polaris RS1 6 inch portal lift kit fits:

• 2018 Polaris RZR RS1 EPS
• 2019 Polaris RZR RS1 EPS
