Product details
This front spindle hub package supplies plain vented 10.75-inch rotors, aluminum hubs, rotor adapter plates and the associated bearing and attachment parts. It does not contain calipers, caliper brackets or brake pads; those must be selected separately to complete the braking assembly. Wilwood Engineering, established by Bill Wood in 1977 and based today in Camarillo, California, manufactures and designs disc brake systems and their components. The product range covers brake rotors, calipers, valves, master cylinders, brake lines and fittings for motorsport, specialized and street-performance applications. Suitability depends on matching each component to the entire brake system.
Technical Details
- Manufacturer part number — 140-1505.
- Wheel bolt circle — 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm.

Fitment & Compatibility
Use the 1934–1948 early Ford drum-spindle geometry shown in DS287, with the exact bearing and wheel interface verified before assembly. Retain the correct spindle adjusting nut and lock. Wheel-face contact overhanging the hub face requires the separate steel spacer; stamped-steel wheels without overhang should use the specified hub shield. The spindle washer may need its outside diameter ground to let the dust cap seat. Confirm all separately chosen caliper and bracket dimensions.
For a fitment check, give PMB Performance the vehicle details and the actual brake and suspension hardware. Our team has over 20 years of experience working through parts compatibility.
