Product details
The A5 inner-bearing arrangement identifies the spindle interface of this late Fox Mustang hub. Its vented-rotor connection uses a separate adapter plate; a matching wheel bolt circle is only one selection check. Founded by Bill Wood in 1977, Wilwood Engineering designs and manufactures disc brake systems from Camarillo, California. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Individual components must be selected for the complete brake system.
Technical Details
- Manufacturer part number: 270-11256

- Rotor interface: 5 x 3.88; this is not the wheel bolt circle
- Compatible rotor-adapter output interface(s): 6 x 6.25, 8 x 7.00; match the actual adapter and rotor
- Product-page drawing references (inches): A = 1.146; D = 2.573; H = 1.589; M = 2.930; N = 1.870; P = 3.030; Q = 0.250. Use the manufacturer drawing for the reference faces.
- Manufacturer bearing / race references: Inner Bearing: 370-2609; Outer Bearing: 370-0882; Inner Hub Bearing - Race: 370-2571; Outer Hub Bearing - Race: 370-0881. References identify compatible service parts and do not mean all bearings are included.
- Related assembly part reference(s): 300-3307; 300-3099; check the kit contents and obtain any separately required parts
- Conflicting published dimensions: Dim D: product page 2.573 inch, DS719 2.57 inch. Confirm the supplied hub and reference faces before using either value.
- Package: One hub; the compatible rotor, rotor adapter or hat and its attachment hardware are selected for the complete conversion

Fitment & Compatibility
Match the documented hub configuration to the installed spindle. Select the corresponding bearings and rotor hardware separately where they are not included; confirm the wheel and caliper clearance.
