KYB 344410 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 344410 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a direct OE-style replacement for select Toyota SUV applications, including the Toyota 4Runner and Toyota FJ Cruiser.

Product Details

The KYB Excel-G 344410 is engineered as an Original Equipment for the Aftermarket replacement, meaning it is calibrated to match the vehicle’s original suspension behavior rather than change it. For Toyota 4Runner rear shock replacement and Toyota FJ Cruiser rear shock replacement, this part supports consistent damping performance and predictable road feel. This part cross-references Monroe Shocks & Struts 37270 for the same application.

Part number 344410 is a fitment-based solution for drivers searching for a rear shock absorber for 2003-2009 Toyota 4Runner or a rear shock absorber for 2007-2009 Toyota FJ Cruiser. It also cross-references Toyota 4853080354 for the same application.
