General XP 4 1000 6 Inch Portal Gear Lift 45% Dual Idler

General XP 4 1000 6 Inch Portal Gear Lift 45% Dual Idler

The General XP 4 1000 6 Inch Portal Gear Lift 45% is engineered for Polaris General XP 4 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 General XP 4 1000 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 when upgrading tire size, you gain controlled torque delivery and improved engine braking for enhanced downhill control.

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 surface area and reduces internal stress by half, resulting in 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.
• Forged Gear Boxes: Stronger than cast or billet aluminum housings.
• Improved Engine Braking: Extends brake life and improves downhill control.
• 13” Stainless Steel Rotors: Slotted for superior heat dissipation.

Heavy-Duty Forged Construction

The General XP 4 1000 6 Inch Portal Gear Lift 45% features forged aluminum gear boxes — the strongest construction method available. Forging creates a denser and tougher structure than cast or billet aluminum, ensuring durability in extreme riding and heavy-duty work 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 machining
