KYB Suspension Shock Absorber P/N:KG5533
Restore factory ride control with the KYB Gas-a-just High Pressure Monotube Gas Shock Absorber (P/N KG4530). This KYB shock absorber is offered as a front OE monotube replacement designed to bring back your Mercedes-Benz's original damping capabilities. It uses two separate 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 that supports a comfortable ride during normal driving and adds performance on demand.
Sold individually; replacing shocks as an axle pair is recommended for balanced ride control.
