Rancho RS5000X Front Shock for Ram

Product Details

The Rancho RS5000X line is tuned for drivers who want more consistent front-end control from a shock absorber that can handle daily driving and uneven road surfaces. On Ram 1500, Ram 2500, and Ram 3500 front suspension applications, RS55221 helps manage compression and rebound movement for steadier steering feel and improved suspension response. This part cross-references Monroe Shocks & Struts (e.g., 34522, 911193) for the same application.

Compatible With select front applications including 2011-2013 Ram 2500, 2011-2012 Ram 3500, 2003-2010 Dodge Ram 2500, 1994-2010 Dodge Ram 3500, 2006-2008 Dodge Ram 1500, and additional listed front-fitment Ram and Dodge Ram configurations. Part number RS55221 is also referenced as RS5221.

What It Helps Address

• Excessive front-end bounce over broken pavement
• Loose or unsettled steering feel from worn shocks
• Reduced control during compression and rebound events
• Front suspension instability on Ram truck applications
• Ride harshness caused by aging OE shock absorbers

Installation Notes

Verify front suspension fitment by year, make, model, and ride-height notes before installation. This shock uses a stem upper mount and loop bushing lower mount, so confirm mount style, sleeve dimensions, and available suspension travel on the vehicle. RS55221 is listed for front positions only and is not a universal replacement.

Quality Assurance

Rancho RS5000X shocks are engineered with a valving strategy focused on controlled on-road and off-road performance. Part number RS55221 is built to match the listed front suspension applications for Dodge Ram and Ram trucks, with fitment data provided for confirmed vehicle coverage.
