Product Details
Rancho RS55039 is a front shock absorber engineered for vehicles with stock height or mild front lift applications listed in the fitment data. It is a direct suspension service part for 1975-1997 Ford and Mazda platforms, including Ford Ranger front suspension, Ford Explorer front suspension, and Mazda B-series front suspension applications. This part cross-references Monroe Shocks & Struts (e.g., 37015) for the same application.
Rancho’s RS5000X line focuses on controlled ride quality through a valving design that responds to both compression and rebound demands. For drivers replacing worn front shocks on a Ford Ranger, Ford Explorer, or Mazda B3000, RS55039 helps restore suspension control, steering stability, and road feel without changing the vehicle’s original suspension layout.
Common Problems This Part Can Address
- Excessive front-end bounce after bumps or dips
- Reduced steering control from worn shock damping
- Nose dive during braking caused by tired front shocks
- Harsh or unsettled ride over uneven pavement
