Product details

This Dynapro Lug Mount rear package is intended for the specified Bronco Big Ford New Style housing end. Black four-piston calipers operate plain-face 12.19-inch drum/rotors, while internal parking-shoe assemblies provide the mechanical holding function. Wilwood Engineering has designed and manufactured disc brake systems and components since Bill Wood founded the company in 1977. From its Camarillo, California base, it supplies motorsport, street-performance and specialized applications with calipers, brake rotors, master cylinders, valves, fittings and brake lines. Selecting those components requires a match to the complete system.

Fitment & Compatibility

The New Style flange and 2.36-inch axle offset distinguish this kit from the 2.00-inch Big Ford Bronco version. Wilwood identifies the matching 1976–1977 heavy-duty arrangement; confirm the actual bearing, flange, wheel pattern and dimensions instead of model year alone. Hoses and cables are separate.
