KYB Suspension Shock Absorber P/N:3440137
KYB 555049 front shock absorber for the 2006-2010 Hummer H3 controls spring and wheel movement with a high-pressure nitrogen gas monotube design. This KYB gas shock absorber is a Gas-a-Just unit, sold as an OE monotube replacement that helps restore the vehicle's original control and handling.
A bouncy ride, nose-dive under braking or oily wetness on the shock can mean a shock is worn. Before replacing it, look at the visible shock body for leaks or damage with the engine off; bushings, mounts or springs can also play a part in a rough ride, and a shop can test them.
This shock absorber fits the 2006-2010 Hummer H3, which takes two, one on each side of the front axle. This listing is one shock; the other side of the front axle is normally done at the same time.

This part cross-references / interchanges with the following part numbers:
Is the KYB 555049 front shock absorber right for the 2006-2010 Hummer H3?
Yes. KYB 555049 fits the front of the 2006-2010 Hummer H3, with one shock on each side of the axle.
Is this KYB shock absorber a gas or oil unit?
This front shock is a high-pressure monotube gas shock. A second chamber of nitrogen gas with a floating piston keeps the gas separate from the oil.
How does this KYB absorber reduce seal wear?
KYB 555049 has an ultra-smooth triple chrome plated piston rod, which reduces seal wear. Fluid leaking can be a cause of shock failure.
How do I tell if a front shock is leaking?
Look for oily wetness on the shock body and rod with the vehicle parked and the engine off. A shop can check the rest, such as how well the shock damps.
Is the Gas-a-Just design meant for towing or heavy wheels?
Yes. Gas-a-Just monotubes are designed for vehicles that work, tow and run larger, heavier tires and wheels.
