KYB KG4006 Shock Absorber - Rear

KYB Gas-a-just Rear Shock Absorber

The KYB Gas-a-just KG4006 is a rear monotube shock absorber built for drivers who want firmer control, quicker response, and consistent damping. It is engineered for select Suzuki Samurai, Hyundai Pony, Honda Civic, and Dodge Colt applications, including rear suspension setups that benefit from added performance over original equipment.

Gas-a-just is KYB’s performance-oriented shock line, using a monotube design with separate gas and oil chambers for responsive damping and reduced fade. The KG4006 is a direct-fit suspension shock absorber for vehicles that work, tow, or run larger, heavier tires and wheels.

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-free operation and instant response
• High-pressure nitrogen gas improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for the specific vehicle application
• Dust cover included

Performance and Fitment Details

KYB Gas-a-just KG4006 uses an air-free hydraulic piston area for control and a high-pressure gas chamber with a floating piston for consistent ride quality during normal driving. That design helps maintain damping performance under load and supports electronic safety systems by keeping suspension behavior closer to the vehicle manufacturer’s intended operation. This part cross-references Monroe Shocks & Struts (e.g., 32207) for the same application.

Compatible With rear suspension applications for 1986-1995 Suzuki Samurai, 1984-1987 Hyundai Pony, 1976-1983 Honda Civic, 1977-1980 Dodge Colt, and 1975 Honda Civic with sealed strut rear fitment. If you are replacing worn rear shocks on a Honda Civic, Suzuki Samurai, or Dodge Colt, the KYB KG4006 provides a direct performance upgrade with monotube control.

What It Helps Address

• Excessive bounce or oscillation from worn rear shocks
• Reduced control during braking, cornering, or load changes
• Shock fade from heat and aeration in demanding driving
• Loose steering feel caused by weak damping response
• Ride instability on vehicles with heavier tires and wheels

Installation Notes and Tips

Verify compressed length, extended length, and stroke before installation: 11.14 in. compressed, 17.44 in. extended, with 6.3 in. of stroke. Upper and lower mount type is E1, and the dust cover is included. Confirm rear position fitment against the vehicle’s suspension configuration before ordering, especially on 1975 Honda Civic sealed strut applications.

Quality Assurance

KYB designs Gas-a-just shocks with vehicle-specific valving and a monotube layout to deliver consistent damping performance and long-term control. Part number KG4006 is built to meet the demands of rear suspension service on compatible Honda Civic, Suzuki Samurai, Hyundai Pony, and Dodge Colt applications.
