Rear Shock Absorber for 1991-1992 BMW 318i & More - KYB KG4539

Help restore your vehicle's original capabilities with this KYB shock absorber — the Gas-a-just High Pressure Monotube Gas Shock (MPN KG4539), a rear-position unit available as an OE monotube replacement. It fits many vehicles, among them the 1991-1992 BMW 318i, the 1991-1992 BMW 318is and the 1988-1991 BMW 325i — see the "Vehicles it fits" section for the full list.

• High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
• Two working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston.
• Triple chrome-plated piston rod: an ultra-smooth surface helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Added damping: adds up to 25% more damping performance over original equipment shocks, for vehicles that work, tow, or run larger, heavier tires and wheels.

As a KYB gas shock absorber, the Gas-a-just also helps keep Electronic Safety Systems performing as designed. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5013.
