Wilwood Red Dynalite-M Front Conversion with 11-Inch One-Piece Rotor/Hubs, GM A/F/X-Body Vehicles Using AFX ProSpindles (Listed 1964–1974 Applications)

Red Dynalite-M calipers accompany one-piece plain-face rotor/hubs in this AFX ProSpindle front conversion. The 11.00-inch rotating assembly is designed around the documented Wilwood spindle interface, not the original GM spindle. BP-10 pads, wheel-bearing hardware and flexlines complete the specified package. Confirm the A/F/X-body application's precise year row and the clearance inside the intended 14-inch or larger wheels. Wilwood Engineering was established in 1977 by Bill Wood in Camarillo, California. The company designs and manufactures disc-brake systems and components, from calipers and rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized installations. Each component must match the rest of the brake system.

Fitment & Compatibility

Use only with the documented Wilwood AFX ProSpindles on the listed GM A-, F- and X-body applications. The manufacturer identifies the primary groups as 1964–1972 A-body, 1967–1969 F-body and 1968–1974 X-body; individual rows retain their specific year and model limits. The required aftermarket spindles are not included, and original spindles are not an equivalent interface. Verify wheel-bolt pattern, hub contact surface, caliper clearance and the completed hydraulic balance. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.

PMB Performance brings 20+ years of parts and fitment experience to brake selection. Send the actual spindle or axle details, existing brake package and wheel measurements for help checking this combination.
