{"product_id":"wilwood-140-16173-d","title":"Wilwood Black Rear AERO4\/EPB Brake Kit for Big Ford Axles with 2.36-Inch Offset, Drilled 14-Inch Spec-37 Rotors","description":"\u003cp\u003eThe drilled-ring version of this Big Ford rear conversion uses black AERO4 hydraulic calipers and separate EPB units. Its two-piece 14-inch rotor assemblies require both correct axle registration and clearance for the parking motors and electrical connectors. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. The range includes calipers, rotors, master cylinders, valves, fittings and brake lines, chosen to suit the mounting and hydraulic requirements of the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 140-16173-D; supplied as one rear axle brake kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic service calipers:\u003c\/strong\u003e AERO4; 4 pistons per caliper; Forged Aluminium body; radial mounting; Stainless pistons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical contents:\u003c\/strong\u003e Separate wheel hubs are not included; mounting hardware supplied; spindles not included.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hats:\u003c\/strong\u003e Aluminum; Black E-Coat; hat offset 1.625 inches.

Nominal 18-inch wheel diameter is only the starting point.\u003c\/p\u003e\u003cp\u003eReview the fitment table below after identifying the rear axle. Confirm housing-flange dimensions, retention hardware, offset, register and wheel pattern against the kit drawing. For a 1990 Lincoln Town Car, identify the actual axle and confirm the specified interface; do not select this conversion from model and year alone.\u003c\/p\u003e\u003cp\u003eThe supplied EPB switch and pigtail connect through a universal harness to the controller and separate parking-caliper motors.
