KYB Gas-a-Just Rear Shock for Porsche 924/944
The KYB Gas-a-Just KG4544 is a rear suspension shock absorber built as an OE-style monotube replacement for select Porsche 924 and Porsche 944 applications. It uses separate hydraulic and high-pressure gas chambers to deliver responsive damping, stable control, and a consistent ride during normal driving.
Key Features
- Monotube design with separate gas and oil chambers for fade-resistant operation and quick response
- Up to 25% more damping performance than original equipment shocks
- Triple chrome plated piston rod helps reduce seal wear and fluid leakage
- Higher gas pressure improves steering response and on-demand control
- Dust cover included for added protection
- Engineered for Porsche 924 and Porsche 944 rear suspension applications
Product Details
Gas-a-Just is KYB’s performance-oriented monotube shock line, designed to restore original suspension function while adding firmer damping control where needed. The KG4544 uses an air-free hydraulic piston and valve area for sensitivity, plus a high-pressure nitrogen gas section with a floating piston to maintain consistent performance. This design is well suited for Porsche 944 rear shock replacement and Porsche 924 rear suspension service where precise control matters. Part number KG4544 is also referenced as a Gabriel 69760 cross-reference for the same application.
What This Shock Helps Address
- Excessive rear-end bounce after bumps
- Reduced damping control from worn OE shocks
- Fluid leakage caused by seal wear
- Delayed response during braking, cornering, or lane changes
- Loss of suspension control on vehicles with heavier wheels and tires
Installation Notes and Tips
- Fits 1985 Porsche 944, rear; recommended OEM replacement, exc. sealed strut; from 1/85

Quality Assurance
KYB designs Gas-a-Just shocks to restore OE monotube performance with application-specific valving and construction. The KG4544 is built to support consistent rear suspension control on Porsche 924 and Porsche 944 models while helping maintain the vehicle’s original handling characteristics.
