Fitment & Compatibility
The specified Ford Bronco brake conversions must use the same hat geometry and rotor interface. Verify the hub register and offset measurement reference before assembling the brake system. Wilwood publishes 1.000 inch on the product and kit pages and 1.300 inches in DS1023/DS1024. Confirm the supplied offset and its reference faces; the measurements are not treated as interchangeable. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
