KYB 349146 Shock Absorber - Rear

KYB Excel-G Rear Shock for Ford Super Duty

The KYB Excel-G 349146 is a rear suspension shock absorber built to restore original ride control, stability, and handling on select Ford Super Duty trucks. It is a recommended OEM replacement for heavy-duty applications where consistent damping and predictable body control matter.

KYB Excel-G shocks are assembled on KYB OE production lines and use OE-quality components with vehicle-specific damping calibration. For Ford F-250 Super Duty and Ford F-350 Super Duty rear suspension service, this part number 349146 is designed to return the truck’s suspension response to factory-style performance rather than alter it.
