Smooth out rough pavement and stay planted off-road with the Rancho RS5000X Suspension Shock Absorber RS55373, a front-position damper built for the 2002-2005 Dodge Ram 1500. Rancho's exclusive Cross Tuned technology pairs a rebound valving system with an advanced compression phase to improve overall on- and off-road handling and performance.

  • Custom-tuned valving: Progressive Engagement Valving is tuned for the vehicle to help reduce initial low-speed impacts, while a Compression Control Valve regulates fluid transfer to absorb impacts without disc flutter.
  • Strong construction: 16mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
  • Temperature handling: Large twin-tube body filled with all-weather fluid for cooler operation and rated to withstand internal temperatures of -40 to 248°F.
  • Fade resistance: Nitrogen gas pressurized to 150 PSI to minimize air-to-oil mixing and reduce damping fade and foaming.

A polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb ride harshness for a smoother ride. Backed by Rancho's Limited Lifetime Warranty.
