KYB Suspension Shock Absorber P/N:3440163
KYB 554406 rear shock absorber for the 2013-2018 Acura RDX controls wheel movement with a high-pressure monotube design. This KYB shock absorber is a Gas-a-just monotube, sold as an OE monotube replacement meant to restore the vehicle's original capabilities.
Fluid on the shock body, a bouncy ride or slower steering response can point to a worn shock. These signs alone do not prove the shock is the problem, since a worn tire can feel similar.
This shock fits the 2013-2018 Acura RDX, which takes two. This listing is one rear shock; the other side of the rear axle is normally done at the same time.
