Wilwood Front Forged Dynalite Drag Conversion for GM/Ford/Mercury Cars (1960–1982), 10.75-Inch Drilled Rotors

Wilwood's four-piston Dynalite front drag kit uses drilled solid steel rotors and aluminum replacement hubs for the specified spindle combinations. The 10.75-inch friction rings are 0.35 inches wide and mount independently of the hubs. Because the model list includes several aftermarket front-suspension arrangements, the spindle configuration matters as much as the vehicle year. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Read the individual model and original disc/drum or Ridetech pin-spindle entry before ordering. Follow DS192 for any required spindle preparation and hub-bearing selection. The wheel mounting face changes by -0.12 inches relative to the stated OE reference, which must be included in the wheel-position check. Supply appropriate hydraulic plumbing and verify the actual wheel's barrel and spoke clearance.
