Can-Am Defender MAX 6 Inch Portal Lift 45% Dual Idler

Defender MAX 6 Inch Portal Lift – 45% Dual Idler Version

The Defender MAX 6 Inch Portal Lift is built for crew machines that demand serious torque, extreme durability, and oversized tire capability. Designed specifically for Can-Am Defender MAX models, this 45% Dual Idler system delivers massive torque multiplication while protecting your drivetrain under heavy load.

If you’re running 40”+ tires and pushing a fully loaded crew rig through deep mud or harsh terrain, this portal lift restores lost power and dramatically reduces stress on belts, axles, differentials, and driveshafts. The 45% gear reduction is the ideal ratio for riders who prioritize torque over top speed.

Why Choose the 45% Dual Idler Design?

• 45% Gear Reduction – Optimized for 40”+ tire setups and heavy crew builds.
• Dual Idler Gears – Doubles gear tooth contact area, reducing internal stress by up to 50%.
• Improved Engine Braking – Extends brake life and improves downhill control.
• Drivetrain Protection – Helps prevent belt burn and axle breakage.

Forged Strength That Outperforms

• Forged Gear Boxes – Stronger than cast or billet aluminum for superior structural integrity.
• Heat-treated alloy steel gears for increased internal and external strength.
• CNC precision-ground machining for accurate fitment.
• Controlled gear lapping for smoother and quieter operation.
