Polaris General 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4 Seater)

Polaris General 6 Inch Portal Gear Lift 45% Dual Idler (2 & 4 Seater)

The Polaris General 6 Inch Portal Gear Lift 45% is engineered for 2-seat and 4-seat Polaris General 1000 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 work applications, trail riding, and aggressive off-road builds.

With a 45% gear reduction, the Polaris General 6 Inch Portal Gear Lift 45% restores low-end power lost from oversized tire upgrades while reducing stress 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 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 more reliable torque transfer under extreme loads.

• 45% Gear Reduction: Ideal for 40”+ tire setups.
• Dual Idler Gears: Increased durability and reduced internal stress.
• Forged Gear Boxes: Stronger than cast or billet aluminum housings.
• Improved Engine Braking: Extends brake life and improves control.
• 13” Precision Stainless Rotors: Slotted for enhanced cooling.

Heavy-Duty Forged Construction

The Polaris General 6 Inch Portal Gear Lift 45% features forged aluminum gear boxes — the strongest construction method in the portal market. Forging creates a denser and tougher structure than cast or billet aluminum, ensuring durability in mud, rocks, and demanding utility environments.

• 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
• 5/16” steel backing plates with welded gussets
• Heat-treated alloy steel gears with CNC precision grinding
