Portal Gear Lift 4 Inch 15% Dual Idler Maverick Sport Defender Commander MAX

Portal Gear Lift 4 Inch 15% Dual Idler Maverick Sport Defender Commander MAX

The 4 Inch 15% Dual Idler Maverick Sport portal system from High Lifter is engineered for riders who want increased ground clearance without sacrificing usable trail speed. Designed for Can-Am Maverick Sport MAX, Defender MAX, and Commander MAX models, this heavy-duty portal gear lift delivers a true 4-inch suspension increase combined with balanced 15% gear reduction.

The upgraded dual idler gear design spreads load across twice as many gear teeth inside the gearbox. By doubling contact surface, internal stress is reduced significantly, resulting in smoother torque transfer, improved reliability, and less strain on belts, axles, differentials, and driveshaft components.

15% Dual Idler Performance Advantage

• 15% gear reduction – Ideal balance of added torque and maintained ride speed.
• Dual idler gear system – Increased tooth engagement reduces stress by half.
• Improved engine braking – Extends brake life and enhances downhill control.
• Reduced drivetrain wear – Helps protect key components under load.

If you’re running larger tires but still want responsive trail and worksite performance, the 15% reduction delivers dependable, controlled power.

Forged Gear Box Strength

This Portal Gear Lift 4 Inch 15% Dual Idler Maverick Sport Defender Commander MAX features forged aluminum housings — stronger than cast or billet alternatives. Forging produces a denser, tougher structure capable of handling shock loads in mud, rocks, and demanding job environments.

• Heat-treated alloy steel gears
• CNC precision-ground machining
• Controlled gear lapping for smoother, quieter performance

Advanced Sealing & Protection

• Dual oil seals on spindle shaft for 100% more sealing area
• Triple-sealed input shaft including protective wiper seal
• High-density Kevlar fiber gaskets (oil & coolant resistant)
• Optional gearbox venting capability for improved cooling

This multi-layer sealing system prevents water intrusion and oil leaks even in harsh mud conditions.
