KYB Suspension Shock Absorber P/N:3440112
KYB 553603 rear shock absorber for the 2003-2007 Cadillac CTS damps suspension movement with a high-pressure monotube gas design. This KYB shock absorber helps restore the control and handling the car was designed with.
A bouncy ride, fluid on the shock body or loose handling can mean a shock is worn, though tires and control arm bushings can sit behind the same symptoms. This listing is one shock absorber, and both rear sides are normally replaced together.
This shock absorber fits the 2003-2007 Cadillac CTS, and the car takes two.
