KYB Suspension Shock Absorber P/N:KG5540

Firm up rear damping and keep your classic BMW planted with the KYB Gas-a-just Suspension Shock Absorber (KG5540). This high-pressure monotube gas shock installs as a rear direct-fit replacement for the 1966-1971 BMW 1600, 1966-1971 BMW 1600-2, 1966-1976 BMW 2002, 1968-1971 BMW 2002TI, and 1971-1974 BMW 2002TII — see the Buyer's Guide tab for engine-level details.

• Twin-chamber monotube design: an air-free hydraulic piston and valve area handles responsiveness and control, while a separate high-pressure nitrogen gas area with a floating piston supports a comfortable ride during normal driving and adds performance on demand.
• Fade-free operation: the high-pressure monotube separates the gas and oil for consistent, fade-free damping and instant response.
• Extra damping: Gas-a-just monotubes are built with additional damping over OE design for vehicles that work, tow, and run larger, heavier tires and wheels — adding up to 25% more damping performance than original equipment shocks.
• Durable piston rod: an ultra-smooth triple-chrome-plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

The higher gas pressure is designed to improve steering response, and the Gas-a-just helps keep Electronic Safety Systems performing as the manufacturer intended.
