A rear end that sags, rides low or bottoms out under load, or a leaf that is cracked or heavily rusted, can mean the leaf helper spring is worn. Worn shackles, bushings or shocks, or the main leaf spring itself, can be behind a sagging rear end too, so find the cause before buying. This listing is one leaf helper spring; the 1973-1979 Ford F-250 takes two, so order two and fit them together.
