Wilwood Front Left-Hand SRP Rotor and Hat for Ford Bronco/Ranger Kits

This left-side SRP replacement retains the 1.25-inch friction thickness of the matching Ford front package. The 13.38-inch drilled-and-slotted ring and integral hat are one iron casting, finished in black electro-coat. Disc brake systems have been Wilwood’s focus since Bill Wood founded the company in 1977. Based in Camarillo, California, Wilwood designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. The rotor is one part of that system and needs compatible pads, calipers and mounting components.
