Product details
This Wilwood Strange Engineering floater hat has a 5.00-inch register and 1.660-inch offset. Check the parking mechanism and 5 x 5.75 flange. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. Its Camarillo, California operation supplies calipers, master cylinders, brake rotors, valves, fittings and lines for specialized, street-performance and motorsport applications. Each component must be chosen to match the complete brake system.

Fitment & Compatibility
For Strange Engineering floater brake systems, compare the replacement with the actual hat and complete brake-kit instructions. A matching flange pattern alone does not establish rotor alignment or caliper clearance. The parking-shoe diameter, anchor arrangement and complete drum-in-hat mechanism must match. A bare hat is not a complete parking-brake assembly.
