RZR Turbo S 6 Inch Portal Gear Lift 45% Dual Idler – (2 Seater)

RZR Turbo S 6 Inch Portal Gear Lift 45% Dual Idler

The RZR Turbo S 6 Inch Portal Gear Lift 45% is engineered for riders running 40” tires or larger who demand reliable torque multiplication and drivetrain protection. Designed specifically for the Polaris RZR Turbo S wide-track platform, this dual idler portal system delivers increased ground clearance, improved engine braking, and reduced drivetrain stress in extreme riding conditions.

With a 45% gear reduction, the RZR Turbo S 6 Inch Portal Gear Lift 45% restores lost torque caused by oversized tires while helping prevent belt failures, axle breakage, and drivetrain damage. If you’re pushing big horsepower and large tires, this gearing solution gives you the power 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 surface 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: Increased durability and reduced stress.
• Improved Engine Braking: Extends brake life and enhances control.
• Massive Torque Increase: Compensates for oversized tire upgrades.

Forged Gear Box Strength

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

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

Precision Gearing & Braking Performance

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

Vehicle Compatibility

This RZR Turbo S 6 Inch Portal Gear Lift 45% fits 2018–2021 Polaris RZR Turbo S EPS, Velocity, Lifted Lime LE, and XP Turbo S models. Designed to maintain factory hub offset and work with control arms built to OEM specifications.
