KYB Suspension Shock Absorber P/N:344438
Bring back factory-tuned damping with the KYB Excel-G Gas Shock Absorber 349001 — a KYB shock absorber built to restore your van's original ride control, stability, and handling rather than change it. It fits the rear position on the 2003-2006 Dodge Sprinter 2500, 2003-2006 Dodge Sprinter 3500, 2002-2006 Freightliner Sprinter 2500, and 2002-2006 Freightliner Sprinter 3500. Made on the same KYB OE assembly lines using OE-quality components, the Excel-G earns its OEA (Original Equipment for the Aftermarket) classification and is a KYB-recommended OEM replacement shock.
Twin-tube, nitrogen gas-charged design: the same gas shock construction and quality components found in KYB's global OEM products.
Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
Vehicle-specific damping valves: hand-assembled in-house to manage tire contact, steering response, and body movement.
Supports safety electronics: helps keep electronic safety systems performing as designed by maintaining proper suspension behavior.
Calibrated to restore the designed control and handling of your Sprinter, the Excel-G is the preferred choice of professional technicians. Shocks wear as a set — replacing both rear units together is best practice for balanced ride control; this listing is for one shock.

Does this KYB gas shock absorber fit my Sprinter?

What is the Excel-G design?
It's a nitrogen gas-charged, twin-tube design using the same OE-quality components as KYB's OEM products, which is why it carries the OEA (Original Equipment for the Aftermarket) classification.
Is this the KYB gas shock absorber Excel-G, and does it change the ride?
Yes, it's the Excel-G. It is calibrated to restore the vehicle's original designed control and handling, not to alter or upgrade the ride.
Do I need to replace shocks in pairs?
This listing is for one shock. Replacing both rear shocks together as a matched set is recommended for balanced, even ride control.
What does the triple-lip fluid seal do?
The triple-lip fluid seal is designed to reduce the chance of oil and gas leaking out of the shock, helping maintain consistent damping performance.
