Rancho Suspension Shock Absorber P/N:RS55234

Dial in on- and off-road control with the Rancho RS5000X shock absorber (MPN RS55234), a rear-position damper that drops in as a direct-fit replacement for the 1997-2001 Ford F-100 Ranger, the 1997-2003 Ford F-150, and the 2004 Ford F-150 Heritage. See the Buyer's Guide tab for engine specifics. At its core is Rancho's exclusive Cross Tuned technology — a rebound valving system and advanced compression phase designed to improve overall handling on and off road.

• Cross Tuned + Progressive Engagement Valving: custom-tuned per vehicle to help reduce initial low-speed impacts and smooth out a rough ride.
• 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.
• Twin-tube, all-weather build: large twin-tube body filled with all-weather fluid rated for internal temperatures of -40 to 248°F, nitrogen gas pressurized to 150 PSI to help minimize air-to-oil mixing, foaming, and damping fade.
• Smooth response: polyurethane rebound bumper, rubber bushings, and a fluon-banded piston work with a low-friction, self-lubricating seal for quicker rebound and smoother compression.

Backed by Rancho's Limited Lifetime Warranty. Sold individually; replacing both rear shocks together is recommended for balanced ride control.
