KYB Suspension Shock Absorber P/N:344338
Restore firm, controlled damping to the rear of your Mercedes-Benz with the KYB Gas-a-just Shock Absorber 553380, a high-pressure monotube gas shock. This KYB shock absorber drops in as a direct-fit rear replacement for the 2004-2005 Mercedes-Benz E320 and 2006-2009 Mercedes-Benz E350, built as an OE monotube replacement to help restore the vehicle's original ride control and handling.
The Gas-a-just runs two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas chamber with a floating piston for a comfortable ride during normal driving and added response on demand.
Rear shocks wear as a pair — replace both rear units together for even, balanced damping. Sold individually.
