Wilwood Black Front Dynalite Hub Kit, 12.19-Inch Drilled/Slotted Rotors for AMC Kelsey-Hayes Disc Spindles

Drilled-and-slotted rotor faces distinguish this AMC front hub conversion. Black four-piston Dynalite calipers and the supplied hubs use the documented Kelsey-Hayes spindle geometry. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility

Measure the 1.25-inch inner and 0.75-inch outer bearing journals identified in DS1025. Verify the bracket spacer stack and wheel-pad support; Bendix disc-brake spindles are outside this configuration.

Documented model groups, subject to each year, submodel and spindle/axle qualification: American Motors Ambassador, AMX, Javelin, Rambler, Rebel, Hornet, Gremlin, Matador, Javelin AMX. Application distinctions include Disc Brake Spindle; AMX / AMX Disc Brake Spindle; Base / Disc Brake Spindle; Disc Brake Spindle, Kelsey Hayes Calipers; AMX / Disc Brake Spindle.

Support the entire wheel mounting pad. An overhanging contact surface calls for 300-11961, the 6.60-inch x 0.20-inch steel spacer (sold separately). For a stamped steel wheel that stays within the hub face, the manufacturer recommends separate shield 300-10716: 6.15-inch diameter and 0.09-inch thickness.

Kelsey-Hayes disc-spindle configuration only, with 1.25-inch inner and 0.75-inch outer bearing journals. Bendix equipment is excluded. Use the DS1025 spacer arrangement to obtain its specified bracket stand-off.

DS1025 specifies 1.25 inches from the spindle backing-plate face to the back of the caliper mounting bracket; use the required spacer arrangement to establish that distance.

Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.
