Product Details

The KYB MonoMax 565039 is a heavy-duty monotube gas shock absorber engineered specifically for trucks, SUVs, and vehicles that handle demanding conditions. With its large bore design, the MonoMax delivers superior stability and control for heavier vehicles, high center of gravity applications, and trucks with increased payload capacity.

Key Features:

  • Monotube design provides fade-free performance that automatically adjusts to changing driving conditions
  • Large bore construction delivers maximum handling, control, and durability for truck applications
  • High-pressure gas charged design maintains consistent damping performance under load
  • Work-ready zinc-coated steel piston ring ensures long-lasting durability
  • Included off-road dust boot protects against dirt, mud, and debris in harsh environments
  • Ideal for vehicles used for towing, hauling heavy loads, off-road driving, or commercial work applications

The KYB MonoMax is built for real-world truck use, providing the strength and performance needed when standard shocks aren't enough. Whether you're towing a trailer, hauling equipment, or navigating off-road terrain, the MonoMax delivers reliable damping control and extended service life.
