KYB Suspension 5640008 MonoMax Heavy Duty Monotube Gas Strut

The KYB MonoMax 5640008 is a heavy-duty monotube gas strut engineered specifically for trucks and SUVs that demand superior handling, control, and durability. Designed for vehicles that tow, haul heavy loads, go off-road, or have been upgraded with larger wheels and tires, this high-pressure monotube strut delivers professional-grade performance in the toughest conditions.

Key Features:

• High-pressure monotube design separates gas and oil for fade-free operation and instant response
• Oversized 46mm piston and bore provides up to 40% more damping than OE twin-tube designs
• Multi-stage valve compression automatically adjusts to changing driving conditions
• Zinc-coated stainless steel piston ring ensures a positive seal in extreme conditions
• Triple chrome-plated piston rod for enhanced durability and corrosion resistance
• Heavy-duty rubber dust boot protects the shaft from off-road debris and prevents premature wear
• Extended length body design with elevated spring seat for leveling applications

The MonoMax's monotube construction provides reduced body roll and pitch compared to standard twin-tube struts, delivering more stable handling for high center-of-gravity vehicles. The larger bore design offers the additional damping force needed when running larger, heavier aftermarket wheels and tires, while the work-ready construction ensures reliable performance whether you're plowing snow, towing a trailer, or navigating off-road terrain. Each strut is sold individually.
