Overview
The Rancho RS55287 is a rear RS5000X Series shock absorber for 2004–2016 Ford F-150 pickups, the 2004 F-150 Heritage and the 2006–2008 Lincoln Mark LT Base. Rancho marks it for a 2.5 in. lift, so it is positioned for trucks lifted about that amount rather than stock height.
The product notes an exclusion for vehicles at 8600 gross vehicle weight and up, so check your truck’s rating against that number before choosing it. Rancho describes the RS5000X valving as a patented rebound system with an advanced compression phase, and both are central to the design.
