Wilwood Front Dynapro 6A Hub Brake Kit, Black, Plain Rotors, Chrysler / Dodge / Plymouth A/B/E/F/J-Body (1973–1989)

Wilwood configures this front Dynapro 6A kit around 12.19 × 0.81-inch rotors for Chrysler / Dodge / Plymouth A/B/E/F/J-Body (1973–1989). The selected black calipers use 6 service pistons each; matching the factory or specified conversion hardware is essential to the complete installation. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc-brake systems for motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must match the complete braking system.

Fitment & Compatibility

DS1536 specifies the 1973–1983 Chrysler, Dodge and Plymouth A/B/E/F/J-body disc-brake spindles. The table below also lists later applications through 1989; confirm that their spindle and bearing arrangement match the drawing before ordering. The supplied aluminum hubs carry 1/2-20 studs. This front brake kit does not include a master cylinder or require a parking-brake cable; those unrelated rear-system notes do not define the front installation. Listed models include Challenger, Charger, Coronet, Dart, Barracuda, Cuda, Duster, Roadrunner, Satellite, Scamp, Valiant, Cordoba, Fury, Aspen, Volare, Lebaron, Diplomat, Monaco, Magnum, New Yorker, Newport, St. Regis, Mirada, Imperial, Caravelle, Fifth Avenue. Verify each row rather than treating the complete year span as fitment for every body.
