RZR XP 1000 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4 Seater)

RZR XP 1000 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4 Seater)

The RZR XP 1000 6 Inch Portal Gear Lift 45% is engineered for riders running 40” tires or larger who need increased torque, drivetrain protection, and improved ground clearance. Designed for both 2-seat and 4-seat Polaris RZR XP 1000 models, this dual idler portal system delivers reliable gear reduction performance for mud, rocks, dunes, and aggressive trail riding.

With a 45% gear reduction, the RZR XP 1000 6 Inch Portal Gear Lift 45% restores low-end power lost from oversized tires while reducing stress on belts, axles, differentials, and driveshafts. Instead of sacrificing reliability when upgrading tire size, you gain controlled torque delivery and improved engine braking for better downhill stability.

Why Choose the 45% Dual Idler Version?

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

• 45% Gear Reduction: Ideal ratio for 40”+ tire setups.
• Dual Idler Gears: Increased durability and reduced internal stress.
• Improved Engine Braking: Extends brake life and improves control.
• Massive Torque Multiplication: Compensates for oversized tire upgrades.

Forged Gear Box Strength

The RZR XP 1000 6 Inch Portal Gear Lift 45% features forged aluminum gear boxes — stronger than cast or billet aluminum alternatives. Forging produces a denser and tougher metal structure that withstands extreme riding conditions.

• Triple input shaft seal including protective 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 cooling
• 5/16” steel backing plates with welded gussets

Precision Gearing & Braking Performance

Each RZR XP 1000 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 performance and long-term durability.

Vehicle Compatibility

This RZR XP 1000 6 Inch Portal Gear Lift 45% fits 2015–2023 Polaris RZR XP 1000 and RZR XP 4 1000 models, including Sport, Premium, Ultimate, High Lifter Edition, Trails and Rocks Edition, Ride Command, Dynamix, Desert Edition, and Fox Edition variants.
