RZR XP Turbo 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4)

RZR XP Turbo 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4 Seater)

The RZR XP Turbo 6 Inch Portal Gear Lift 45% is engineered for riders running 40” tires or larger who demand serious torque multiplication and drivetrain protection. Designed for both 2-seat and 4-seat Polaris RZR XP Turbo models, this dual idler portal system delivers increased ground clearance, stronger low-end power, and improved engine braking for extreme off-road performance.

With a 45% gear reduction, the RZR XP Turbo 6 Inch Portal Gear Lift 45% restores lost torque caused by oversized tires while reducing stress on belts, axles, differentials, and driveshafts. If you’re tired of burning belts and breaking components after upgrading your tire size, this heavy-duty gearing solution provides the strength and reliability your machine needs.

Why Choose the 45% Dual Idler Version?

The dual idler design spreads load across twice as many gear teeth compared to single-idler portals. This doubles the contact area and reduces internal stress by half, giving you more reliable torque transfer under aggressive riding conditions.

• 45% Gear Reduction: Ideal for 40”+ tire setups.
• Dual Idler Gears: Reduced internal stress and improved durability.
• Improved Engine Braking: Extends brake life and enhances downhill control.
• Massive Torque Increase: Restores performance lost from oversized tires.

Forged Gear Box Construction

The RZR XP Turbo 6 Inch Portal Gear Lift 45% features forged aluminum gear boxes — stronger than cast or billet alternatives. Forging creates a denser, tougher metal structure for maximum impact resistance in mud, rocks, and high-load conditions.

• Triple input shaft seal including protective wiper seal
• Dual spindle oil seals for 100% more sealing area
• High-density Kevlar fiber gaskets (oil & coolant resistant)
• Optional gear box venting provision for improved cooling
• 5/16” steel backing plates with welded gussets

Precision Gearing & Braking Performance

Each RZR XP Turbo 6 Inch Portal Gear Lift 45% includes 13” precision-ground stainless steel rotors. The slotted rotor design enhances heat dissipation while access holes simplify installation and service. Heat-treated alloy steel gears are CNC precision ground and lapped for smoother, quieter performance and long-term strength.

Vehicle Compatibility

This RZR XP Turbo 6 Inch Portal Gear Lift 45% fits 2016–2021 Polaris RZR XP Turbo and RZR XP 4 Turbo EPS models, including Dynamix and Fox Edition variants. Designed to maintain factory hub offset and work with control arms built to OEM specifications.
