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.

PMB Performance has over 20 years of parts experience. Share the VIN and any changes to the axle, upright or wheels before ordering if the brake configuration is uncertain.
