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

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

The RZR PRO XP Portal Gear Lift 6 Inch 45% dual Idler is engineered for serious riders running 40” to 44” tires who demand reliable torque multiplication and drivetrain protection. Designed for both 2-seat and 4-seat Polaris RZR PRO XP models, this dual idler system delivers increased ground clearance, improved engine braking, and reduced drivetrain stress in extreme riding conditions.

With a 45% gear reduction, the RZR PRO XP Portal Gear Lift 6 Inch multiplies torque at the wheels while reducing strain on belts, axles, differentials, and driveshafts. If you’ve upgraded to oversized tires and experienced loss of power or component failures, this gearing solution restores performance while protecting critical drivetrain parts.

Why Choose the 45% Dual Idler Version?

The dual idler design spreads load across twice the gear teeth compared to single-idler portals. This doubles the contact area and reduces internal stress by half, providing more reliable torque transfer under heavy load.

• 45% Gear Reduction: Ideal for 40”–44” tire setups.
• Dual Idler Gears: Reduced internal stress and improved reliability.
• Forged Gear Boxes: Stronger than cast or billet aluminum housings.
• Improved Engine Braking: Extends brake life and improves downhill control.
• Maximum Recommended Tire Size: 44”.

Heavy-Duty Forged Construction

The RZR PRO XP Portal Gear Lift 6 Inch  45% uses forged aluminum gear boxes — the strongest construction method available in the portal market. Forging produces a denser, tougher structure than cast or billet aluminum, giving you more durability in mud, rocks, and aggressive trail riding.

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

Precision Gearing & Braking Performance

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

Vehicle Compatibility

This RZR PRO XP 6 Inch Portal Gear Lift 45% fits 2020–2026 Polaris RZR PRO XP Sport, Premium, Ultimate, Rockford Fosgate editions, and PRO XP 4 models. Designed to maintain factory hub offset and work with control arms built to OEM specifications.
