What's in the Box

Info

Replace those old drum brakes with modern rear disc brakes. Steel rotor hat mounts .81" x 11-3/4" Pro-lite vented iron rotors and calipers to 3" tube rear end.  Complete with rotors, hats, calipers (7/16"-20 inlets), brackets, brake pads, caliper brackets and slider bolts. 

Hat fits 5 lug hubs with 4-1/2", 4-3/4", or 5" bolt circle.

Installation note: Due to a wide variation in daimeters of axle flanges and center hubs from manufacturers, it may be necessary to turn these diameters down to the proper dimensions.
