KYB Suspension Shock Absorber P/N:3440137
Firm up rear-end control on your Mercedes-Benz GLK with the KYB Gas-a-just shock absorber (P/N 553386), a high-pressure monotube gas shock. This KYB shock absorber drops in as the correct monotube OE replacement for the rear axle of the 2013-2015 Mercedes-Benz GLK250 and 2010-2015 Mercedes-Benz GLK350, helping restore the GLK's designed control and handling.
The Gas-a-just uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a second high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and added performance on demand.
Built for vehicles that work, tow, and run larger, heavier tires and wheels. Sold individually; replace both rear shocks together as a matched pair for balanced ride and handling.

This part cross-references / interchanges with the following part numbers:
What vehicles does this KYB gas shock absorber fit?
It's a rear shock absorber for the 2013-2015 Mercedes-Benz GLK250 and the 2010-2015 Mercedes-Benz GLK350. See the Buyer's Guide tab to confirm your exact vehicle.
Is this a monotube or twin-tube shock?
It's a high-pressure monotube gas design. The monotube layout separates the gas and oil for fade-free operation and instant response.
What does the high-pressure nitrogen gas do?
A separate high-pressure nitrogen chamber with a floating piston provides a comfortable ride during normal driving and adds performance on demand, while the higher pressure helps improve steering response.
Does this listing include both rear shocks?
No. This shock absorber is sold individually. For balanced ride and handling, it's best to replace both rear shocks together as a matched pair.
How is the KYB Gas-a-just built to resist leaking?
It uses an ultra-smooth triple chrome-plated piston rod that reduces seal wear, since fluid leaking can be a cause of shock failure.
