KYB 344382 Shock Absorber - Rear

KYB Excel-G Rear Shock for Super Duty

The KYB Excel-G 344382 is a rear suspension shock absorber for 1999-2004 Ford F-250 Super Duty and Ford F-350 Super Duty applications. It is built to restore original ride control, stability, braking response, and handling balance without changing the vehicle’s designed suspension behavior.

As part of the KYB Excel-G line, this shock is made on KYB OE assembly lines using OE-quality components and calibration focused on returning factory performance. For Ford Super Duty rear suspension service, the 344382 is a direct-fit OE-style replacement choice.

Detailed Description

The KYB Excel-G 344382 is engineered for drivers who want the rear suspension on a 1999-2004 Ford F-250 Super Duty or Ford F-350 Super Duty to perform as originally designed. KYB builds the Excel-G on the same production lines used for original equipment supply, and the damping calibration is set to recover factory ride control rather than alter it. This makes the 344382 a practical replacement for worn rear shocks on Super Duty trucks that need stable handling, predictable braking feel, and consistent lane-change response.

This part cross-references Monroe Shocks & Struts 34685 for the same application. Part number 344382 is also listed as a rear replacement option for Ford F-250 Super Duty and Ford F-350 Super Duty service work.

What It Helps Address

• Excessive rear bounce or oscillation after bumps
• Reduced stability during braking or lane changes
• Loose or unsettled rear-end handling on rough roads
• Uneven tire contact caused by worn damping
• Suspension noise or fluid leakage from aging shock absorbers
