Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.

Fitment & Compatibility

These 12.19 × 0.81-inch front brakes require the documented early Mopar A-body factory disc spindle. The selected years differ by model: Barracuda coverage ends in 1969, while Duster and Scamp start later than Dart/Valiant. DS-1300 states the original five-on-4.50-inch lug-pattern condition; inspect the actual spindle/hub arrangement before ordering. Aluminum hubs, bearings, seals and 1/2-20 studs are included and provide dual 5 × 4.50/4.75-inch wheel patterns. Hoses are separate; select the documented line option for the actual fittings and routing. Any separately installed two-bolt master cylinder may need the required four-bolt mounting adapter, which Wilwood does not supply. Check the wheel drawing even where a 15-inch wheel is nominally allowed.

Listed models: Dart; Barracuda; Valiant; Duster; Scamp. See the supplied table below for each year, submodel and equipment condition.
