Ranger 900 Crew 6 Inch Portal Gear Lift 45% Dual Idler (Old Body)

Ranger 900 Crew 6 Inch Portal Gear Lift 45% Dual Idler (Old Body Style)

The Ranger 900 Crew 6 Inch Portal Gear Lift 45% is engineered for Polaris Ranger Crew XP 900 old body style models running 40” tires or larger. This heavy-duty dual idler portal system delivers increased ground clearance, improved torque multiplication, and superior drivetrain protection for mud, trails, and demanding work applications.

With a 45% gear reduction, the Ranger 900 Crew 6 Inch Portal Gear Lift 45% restores low-end power lost from oversized tire upgrades while reducing strain on belts, axles, differentials, and driveshafts. Instead of sacrificing reliability, you gain stronger pulling power and improved engine braking for better downhill control and heavy-load performance.

Why Choose the 45% Dual Idler Version?

The dual idler gear configuration 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 more reliable torque transfer under heavy loads.

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

Forged Gear Box Strength

The Ranger 900 Crew 6 Inch Portal Gear Lift 45% features forged aluminum gear boxes — stronger than cast or billet alternatives. Forging produces a denser, tougher structure that withstands extreme off-road conditions and heavy utility work.

• 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 improved cooling
• 5/16” steel backing plates with welded gussets

Precision Gearing & Braking Performance

Each Ranger 900 Crew 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 durability.
