KYB KG4192 Shock Absorber - Rear

KYB Gas-a-just Rear Shock Absorber

The KYB Gas-a-just KG4192 is a monotube rear shock absorber built as an OE-style replacement for vehicles that need firmer control and consistent response. It is engineered for applications such as the Hyundai Scoupe, Hyundai Excel, Mitsubishi Precis, Dodge Colt, Mitsubishi Cordia, and Mitsubishi Tredia.

With a high-pressure gas design and vehicle-specific valving, the KYB Gas-a-just KG4192 is aimed at restoring suspension control on older compact cars while improving response for daily driving, towing, and heavier wheel-and-tire setups.

Key Features

• Monotube shock absorber design for direct response and stable damping
• Up to 25% more damping performance than original equipment shocks
• Separate gas and oil chambers for fade-resistant operation
• Vehicle-specific components and valving for the listed applications
• High gas pressure for quicker steering response
• Triple chrome plated piston rod to help reduce seal wear
• Dust cover included
• R-stop and B-stop design features noted by KYB

Product Details

The Gas-a-just line is KYB’s monotube shock absorber series for drivers who want OE replacement fit and added control. The KG4192 uses an air-free hydraulic working area for damping response and a separate high-pressure nitrogen gas section with a floating piston to maintain consistent performance. That layout helps the shock react quickly and stay controlled during normal driving, while also providing additional damping when the suspension is working harder. This part cross-references Monroe Shocks & Struts (e.g., 5877) for the same application.

Compatible With rear suspension applications on 1991-1995 Hyundai Scoupe, 1986-1994 Hyundai Excel, 1987-1994 Mitsubishi Precis, 1984-1991 Dodge Colt, 1979-1981 Dodge Colt, 1983-1988 Mitsubishi Cordia, 1983-1988 Mitsubishi Tredia, and 1984 Dodge Colt. Part number KG4192 is also referenced in aftermarket catalogs alongside Gabriel 69689.

What It Helps Address

• Excessive bounce or poor body control from worn rear shocks
• Delayed steering response caused by weak damping
• Fade during repeated suspension movement or heavier use
• Reduced stability on vehicles with larger, heavier tires and wheels
• Suspension performance loss that can affect electronic safety system operation

Installation Notes and Tips

Install KG4192 according to the vehicle manufacturer’s instructions. For the listed Hyundai, Mitsubishi, and Dodge applications, replace the suspension strut and coil spring assembly as directed in the fitment notes. Verify compressed length, extended length, stroke length, and upper/lower mount types before installation to confirm proper rear suspension fitment.

• Compressed length: 10.75
• Extended length: 15.55
• Stroke length: 4.8
• Lower mount type: E2(12X32)
• Upper mount type: E2(12X60)

Quality Assurance

KYB designs the Gas-a-just line as an OE monotube replacement with application-specific valving and construction intended to restore original suspension capability. The KG4192 uses a high-pressure monotube layout and a chrome piston rod to support consistent operation and reduced seal wear over time.
