Founded in 1977 under Bill Wood, Wilwood Engineering operates from Camarillo, California. The company designs and manufactures disc brake systems and the calipers, rotors, master cylinders, valves, fittings and lines used within them. Its motorsport, street-performance and specialized applications depend on compatible brake components.

Fitment & Compatibility

Wilwood specifies this Dynapro Single family for four-wheel-disc drag cars weighing under 2,400 pounds. Confirm the Chassis Engineering strut and mounting bracket with Wilwood; no installation sheet is linked for this exact kit. Verify wheel clearance and the complete brake system rather than relying on the generic factory-disc-spindle field.
