KYB Gas-a-Just Shock Absorber KG6004

The KYB Gas-a-Just KG6004 is a monotube suspension shock absorber built for trucks and other vehicles that carry load, tow, or run larger wheels and tires. It delivers quicker response than a conventional twin-tube design and maintains consistent damping without fade from aeration.

For drivers searching for a KYB Gas-a-Just shock absorber for heavy-duty truck suspension service, the KG6004 is engineered to add control while preserving a comfortable ride during normal driving. It is a direct-fit suspension shock absorber for compatible applications and is commonly cross-referenced with Monroe Shocks & Struts 65102.

Key Features

  • Adds up to 25% more damping performance over original equipment shocks
  • Monotube design separates gas and oil for fade-free operation and instant response
  • High-pressure nitrogen gas chamber improves steering response
  • Triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Designed for heavy-duty trucks and vehicles with larger, heavier tires and wheels
  • Dust cover included

Product Details

The Gas-a-Just line uses two working chambers: an air-free hydraulic section for control and a high-pressure gas section with a floating piston for rapid adjustment. That design helps the shock react quickly when road conditions change, while staying composed during everyday driving. The KG6004 measures 16.57 inches compressed, 26.61 inches extended, and provides 10.04 inches of stroke.

This part number, KG6004, is suited for buyers comparing KYB shock absorber replacement options for truck suspension repair, towing stability, and steering feel. It is also a practical choice for drivers looking for a KYB KG6004 replacement shock with monotube performance characteristics.

What It Helps Address

  • Excessive body bounce after bumps or dips
  • Reduced steering response from worn shocks
  • Fade in damping performance during demanding driving
  • Suspension instability when towing or carrying heavier loads
  • Premature seal wear related to fluid leakage

Installation Notes and Tips

Verify upper and lower mount types before ordering: E1-L/E(26) upper mount and E1L/E(26) lower mount. Confirm compressed length, extended length, and stroke against the original shock to ensure proper suspension travel and ride height. Because fitment data is not provided here, match the KG6004 to the exact vehicle application before installation.

For shoppers comparing KYB Gas-a-Just KG6004 against other shock absorber options, this part is intended for direct replacement use in the correct application and should be installed with attention to mounting orientation and suspension condition.

Quality Assurance

KYB is a long-established suspension manufacturer known for OE-style engineering and controlled damping performance. The Gas-a-Just design is built to maintain consistent response under demanding conditions, supporting vehicles that work, tow, and carry heavier wheel and tire setups.
