Sharpen every mile with the Rancho RS5000X Suspension Shock Absorber RS55118 — a Rancho shock absorber built around the brand's exclusive Cross Tuned technology, which pairs a rebound valving system with an advanced compression phase to improve overall on- and off-road handling and performance. It's a direct-fit replacement for a huge range of trucks, vans and SUVs, including the 1980-1996 Ford F-150, the 1987-1995 Jeep Wrangler and the 1966-1977 Ford F-250 — see the Buyer's Guide tab for the full list.

  • Cross Tuned handling: exclusive rebound valving and advanced compression phase help improve control on and off road.
  • Minimizes a rough ride: Progressive Engagement Valving is custom-tuned per vehicle to help reduce initial low-speed impacts.
  • Strong and durable: 16mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, 35mm sintered iron piston and a polyvinyl protective boot.
  • Built for heat and control: large 2-1/4 in twin-tube body filled with all-weather fluid and able to withstand internal temperatures of -40 to 248°F, nitrogen pressurized to 150 PSI to reduce fade and foaming.

Depending on the application it serves the front, rear or front inner position; backed by Rancho's Limited Lifetime Warranty.
