Super Bell's Power Stopper Front disc brake kits have been designed with the 3,000 lb. and over cars in mind. Fits both the '37-'48 Ford passenger car spindle and the '48-'56 Ford truck spindles. Cast iron hubs and 1" vented rotors provide all the stopping power your hot rod will ever need. Comes with a stamped steel dust shield that protects brakes from dirt and weather. Cast iron hubs can be ordered with your choice of 5x4 1/2", 5x4 3/4", 5x5" or 5x5" 1/2" bolt patterns to fit most applications.
