Wilwood Front ProMatrix D1631A Pads for F-350/F-450 Super Duty Dual-Rear-Wheel Packages (2012)

The D1631A ProMatrix front pad is the nominal 0.69-inch specification associated with the listed dual-rear-wheel Super Duty packages. Frame width and rear-wheel layout help distinguish it from the thicker D1631 selection offered in the same model year. Bill Wood founded Wilwood Engineering in 1977. From its base in Camarillo, California, Wilwood designs and manufactures disc brake systems and components for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Compatibility with the complete brake system governs selection of the individual components.

Fitment & Compatibility

Check F-350 or F-450, two- or four-wheel drive and the Wide Frame DRW condition where specified. A 2012 model-year match alone is not enough when chassis or axle equipment differs.

The dimensional illustration labels a 2012 F-250 front application and shows the same 0.690-inch thickness for inner and outer pads. That caption identifies another use of the plate; it does not replace the F-350/F-450 DRW qualifications listed here or establish fitment on an unlisted F-250 configuration.

Application coverage, subject to the brake and equipment qualifications below: Ford F-350 Super Duty (2012); Ford F-450 Super Duty (2012).

Use the fitment table below to confirm the exact year, model, trim and brake configuration. Compare the pad outline and installed caliper where a vehicle has been modified.

Use PMB Performance's 20-plus years of experience when the fitted brake package is uncertain. A caliper reference and comparison with the removed pad are useful alongside the vehicle's year and model.
