Wilwood 12.19-Inch Drilled Front Rotor and Hub Package for Early A-Body Mopars with Black Dynalite Calipers

Black Dynalite calipers, drilled rotors and dual-pattern hubs suit listed early A-body spindles. Check wheel clearance and separate hose selection. Wilwood Engineering designs and builds disc brake systems in Camarillo, California. Bill Wood established the company in 1977; it supplies brake rotors, calipers, master cylinders, valves, fittings and lines for specialized applications, street performance and motorsport. The complete brake system determines which individual components are appropriate.

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.
