The KYB Gas-a-Just KG5550 is a monotube suspension shock absorber built to restore OE-style control with quicker response under load. It uses separate hydraulic and high-pressure gas chambers to deliver consistent damping for everyday driving, towing, and vehicles with larger tires and wheels.

Key Features

  • Monotube design with separate gas and oil chambers for fade-resistant operation
  • Up to 25% more damping performance than original equipment shocks
  • High-pressure nitrogen gas helps improve steering response
  • Triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Dust cover included for added protection
  • Lower and upper mount type: S1
  • Compressed length: 12.01 in; extended length: 19.29 in; stroke length: 7.28 in

Product Details

Gas-a-Just is KYB’s monotube shock line for drivers who want firmer control without giving up normal-road comfort. The KG5550 is engineered with valving and components specific to Triumph applications, and its high-pressure design helps the shock react quickly when the suspension is working harder. This part cross-references Gabriel 82139 for the same application. Use KYB KG5550 when replacing a worn suspension shock absorber on compatible Triumph models, including Triumph suspension shock absorber applications where quicker rebound control and stable handling are needed.

Common Problems This Part Can Help Solve

  • Excessive bouncing after bumps or dips
  • Loose steering feel or delayed response
  • Reduced control when carrying load or towing
  • Shock fade during repeated suspension movement
  • Oil seepage from a worn shock body or seal

Installation Notes and Tips

Verify mount style, compressed length, extended length, and stroke before installation. Inspect surrounding suspension components, bushings, and hardware for wear before replacing the shock. Because fitment data is not provided here, confirm the application by year, make, model, and position before ordering the KYB KG5550.

Quality Assurance

KYB designs Gas-a-Just shocks as OE-style monotube replacements to restore original suspension function and maintain consistent damping performance. The monotube construction and high-pressure gas charge are intended to support stable operation and responsive handling in demanding driving conditions.
