Rancho RS5000X Rear Shock for Ford Trucks

The Rancho RS5000X RS55234 is a rear suspension shock absorber built for select Ford F-150, F-150 Heritage, and F-100 Ranger applications. It uses Rancho’s RS5000X valving approach with advanced compression control to improve on-road stability and off-road damping response.

Key Features

  • Rear suspension shock absorber for select Ford truck applications
  • Rancho RS5000X valving for controlled compression and rebound response
  • Compressed length: 16.13 in; extended length: 27.03 in
  • Travel length: 10.9 in
  • Dust shield included for added shaft protection
  • Extended bumper stop included; compressed bumper stop not included
  • Upper mount: stem mount with 2.375 in stem length and 3/8 in-16 thread pitch
  • Lower mount: loop bushing and sleeve mount with 12 mm sleeve ID and 1.5 in sleeve OAL

Product Details

Rancho RS5000X shocks are tuned to deliver more consistent damping across changing road conditions, making them a practical upgrade for drivers who want firmer rear suspension control without changing the vehicle’s basic setup. The RS55234 part number is listed for rear position use on 1997-2003 Ford F-150, 2004 Ford F-150 Heritage, and 1997-2001 Ford F-100 Ranger applications with the specified suspension and GVW requirements. This part cross-references Monroe Shocks & Struts (e.g., 34658, 911134) for the same application.

What It Helps Address

  • Excessive rear-end bounce over uneven pavement
  • Reduced control during load changes or towing-related suspension movement
  • Harsh or inconsistent rear shock response
  • Worn shock performance that can affect ride stability
  • Rear suspension damping issues on lifted or stock-height listed Ford truck applications

Installation Notes

Compatible With 1997-2003 Ford F-150, rear; 2004 Ford F-150 Heritage, rear; and 1997-2001 Ford F-100 Ranger, rear, when the listed GVW and suspension conditions are met. Verify compressed length, extended length, and mounting style before installation to confirm proper suspension travel and fitment. The RS55234 uses a stem upper mount and loop lower mount, so the existing mounting points must match those specifications. For lifted applications, confirm the rear raised height and Rancho suspension system requirements shown in the fitment data.

Quality Assurance

Rancho RS5000X shocks are engineered as a performance-oriented suspension replacement with application-specific valving and construction details intended to support consistent damping in daily driving and off-road use. Part number RS55234 is cataloged for direct-fit rear applications listed above.
