KYB Suspension Shock Absorber P/N:344438
KYB 346603 rear shock absorber for the 2003-2009 Chevrolet C4500 Kodiak and other vehicles damps rear suspension movement to help restore original ride control. This KYB shock absorber is a recommended OEM replacement shock for heavy-duty trucks and commercial vehicles.
A rear shock that leaks oil, lets the truck keep bouncing after bumps or wears tires unevenly may be worn out. Worn spring bushings, loose mounts or tire problems can show the same signs, so pin down the cause before you buy. This listing is one shock, and both rear shocks are normally replaced together.
Besides the 2003-2009 Chevrolet C4500 Kodiak, it fits the 2003-2009 Chevrolet C5500 Kodiak and the 2003-2009 GMC C4500 Topkick, among many others. Driving something else? Look up your truck in the "Vehicles it fits" section to see whether this shock is listed for it.
