The Eibach HD Pro-Lift kit provides heavy-duty replacement rear springs engineered for sixth-generation Ford Bronco applications. This HD Pro-Lift spring serves as a direct replacement for the PTCO rear setup, restoring ride height and support where additional rear load capacity or lift is desired. It’s a factory-style upgrade that maintains predictable handling while addressing rear‑end sag under load.
