KYB Suspension Shock Absorber P/N:555609
KYB 554378 rear shock absorber for the 2009-2017 Chevrolet Traverse and other vehicles uses a high-pressure nitrogen gas chamber to damp suspension movement. This KYB shock absorber adds up to 25% more damping than original equipment shocks.
A worn rear shock can show up as a bouncy or floating ride, oil on the shock body or a clunk over bumps, though worn tires or rear suspension bushings can be behind the same signs, so find the cause before replacing it.
The listing covers a wide range of Chevrolet, GMC, Buick and Saturn models, led by the 2009-2017 Chevrolet Traverse, the 2007-2016 GMC Acadia and the 2008-2017 Buick Enclave. Two go on the rear axle, and both sides are normally replaced at the same time. Open the "Vehicles it fits" section to check your exact model and engine.

This part cross-references / interchanges with the following part numbers:
Is this KYB rear shock absorber right for the 2009-2017 Chevrolet Traverse?
Yes. KYB 554378 is listed for the 2009-2017 Chevrolet Traverse, which takes two at the rear; for other models, open the "Vehicles it fits" section.
Does this KYB gas shock absorber fit the 2007-2016 GMC Acadia?
Yes. KYB 554378 is listed for the 2007-2016 GMC Acadia, and its components and valving are designed specifically for GM SUVs.
How does a KYB gas a just shock absorber differ from a twin-tube shock?
It is a monotube with an air-free hydraulic piston and valve area and a separate high-pressure nitrogen chamber with a floating piston, so it does not fade from aeration.
Can a leaking rear shock be spotted by eye?
Yes: with the engine off, look at the shock body and rod for oily wetness, since fluid leaking can be a cause of shock failure. The KYB 554378 has a triple chrome plated piston rod to reduce seal wear.
Does the KYB 554378 replace part number 20757505?
Yes. 20757505 is one of the numbers this KYB 554378 replaces, along with 23147603 and 25822946.
