RS5000X Product Line Details

Rancho RS5000X shocks are built around a valving system tuned for controlled damping across changing road surfaces. For drivers looking for a front shock for a 2000-2005 Ford Excursion, front, or a 1999-2004 Ford F-250 Super Duty, front, the RS55267 provides a direct-fit suspension shock absorber solution. It also matches 1999-2004 Ford F-350 Super Duty, front applications. This part cross-references Monroe Shocks & Struts (e.g., 34518, 34686) for the same application.

What This Shock Helps Address

• Excessive front-end bounce over bumps and uneven pavement
• Loose or unsettled steering feel from worn shock damping
• Reduced control during braking, cornering, or load transfer
• Harsh suspension movement caused by aging front shocks
• Inconsistent ride quality on mixed on-road and off-road use

Installation Notes

Compatible With 2000-2005 Ford Excursion, front; 1999-2004 Ford F-250 Super Duty, front; and 1999-2004 Ford F-350 Super Duty, front. Verify mount style, compressed length, and extended length before installation. This shock uses loop bushing and sleeve mounts at both ends, so confirm the vehicle’s original hardware and mounting dimensions match the listed specifications.

Quality Assurance

Rancho RS5000X shocks are engineered with application-specific valving and compression control for consistent suspension performance. RS55267 is built to match the listed fitment and mounting dimensions for the specified Ford front suspension applications.
