Fits select 1970-1979 Ford F-100, F-150, and F-250 pickup trucks.

The Rancho RS5000X shock absorber utilizes a unique Cross Tuned technology with an exclusive rebound valving system and advanced compression phase to improve handling both on and off-road. Engineered with Progressive Engagement Valving, these shocks are custom-tuned for each application to reduce initial impacts at low speeds and minimize ride harshness. The twin-tube body is nitrogen-gas pressurized to 150 PSI, reducing air-to-oil mixture to prevent damping fade and foaming during heavy use.
