KYB Excel-G Rear Shock for Sprinter 3500

The KYB Excel-G 344409 is a rear suspension shock absorber for the 2003-2006 Dodge Sprinter 3500 with dual rear wheels. It is built to restore original ride control, stability, and steering response while maintaining the vehicle’s designed handling balance.
