Product Details

The KYB Gas-a-Just 5510012 is a high-pressure monotube gas shock absorber engineered to deliver superior performance and fade-free operation. Unlike traditional twin-tube designs, this monotube construction provides instant, automatic adjustments to match your driving demands while maintaining consistent damping control under all conditions.

Key Features:

  • Monotube design eliminates shock fade caused by aeration and foaming
  • Dual-chamber construction with separate hydraulic and nitrogen gas areas
  • Air-free hydraulic piston and valve system for precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston design
  • Automatically adapts from comfortable daily driving to performance handling on demand
  • Available as direct OE monotube replacement or performance upgrade for OE twin-tube systems
  • Larger diameter piston for increased stroke length and improved heat dissipation

The Gas-a-Just's innovative two-chamber design separates the hydraulic damping fluid from the pressurized nitrogen gas using a free-floating piston. This configuration maintains consistent pressure on the damping fluid, preventing aeration while providing the compliance needed for a comfortable ride and the firm control required for spirited driving and heavy loads.
