Fitment & Compatibility

For the Small Ford flange with a measured 2.50-inch axle offset, this black low-profile package supplies plain 11.00 × 0.81-inch vented iron rotors with integral parking hats and internal shoes. Measure offset between the wheel-side axle-flange face and housing-flange face. The same nominal offset on a new-style Big Ford axle is a different interface, and the 2.66-inch Small Ford kit is a separate configuration. Stock 1990 Lincoln Town Car compatibility is unverified. Check the actual housing, bearings and register before relying on the vehicle entry below. Parking cables, clevises, adapters and hydraulic hoses must be purchased separately. Verify the specified flange-diameter limit and chamfer, 3.06-inch rotor center and supplied 2.80-inch register ring. Larger studs may require rotor-hole machining. Use the clearance drawing to assess the conditional 14-inch wheel guidance.
