{"product_id":"wilwood-140-17874-d","title":"Wilwood Big Ford New Style Dual-XRD Rear Drag Brake Conversion, 2.50-Inch Offset and Drilled Lug-Drive Rotors","description":"\u003cp\u003eDual XRD calipers per rear wheel pair with drilled Super Alloy rotors for a measured Big Ford New Style axle. Confirm offset and hydraulic layout. The wheel-end assembly is selected by its measured housing-end interface and racing hydraulic arrangement. From Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood, the company produces calipers, brake rotors, master cylinders, valves, fittings and brake lines. Component selection depends on the requirements of the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRotor \/ hat axle-flange drilling: 5 X 4.50; 5 X 4.75; 5 X 5.00 inches; this does not change the retained hub or axle wheel pattern\u003c\/li\u003e\n\u003cli\u003eHydraulic flexlines: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eMounting hardware: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eNot included: spindles, wheel hubs, master cylinder or brake booster\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 140-17874-D\u003c\/li\u003e\n\u003cli\u003eBrake assembly: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eCalipers: Forged XRD Lug Mount; 4 pistons per caliper; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eCaliper mounting: Lug\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-28\u003c\/li\u003e\n\u003cli\u003ePiston material: Stainless\u003c\/li\u003e\n\u003cli\u003eHydraulic caliper inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor dimensions and construction: 11.25 × 0.35 inches; Super Alloy; Drilled\u003c\/li\u003e\n\u003cli\u003eWheel-size reference: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eAxle mounting interface: Big Ford New Style; measured axle offset 2.50 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe dual-caliper configuration has two XRD units at each rear wheel and requires a Big Ford New Style housing end with 2.50-inch measured axle offset. Confirm the hydraulic circuits and clearance for both calipers before selecting it. The 11.25-inch Super Alloy rotors engage dynamic lug-drive hats and are retained with internal snap rings; the axle wheel pattern is unchanged by the hat drilling. Match the bearing retainer, axle registration and wheel drawing in DS-1607 and supply the hydraulic hoses separately. The 1990 Lincoln Town Car row below requires verification of the actual rear axle; its model name alone is insufficient.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17874-D\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1607.pdf\"\u003eWilwood installation and compatibility information\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eAxle measurement worksheet\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitFitmentApp.aspx?minorcat=XRD%20Dual%20SA%20Scalloped%20Lug%20Drive%20Dynamic%20Rear%20Drag%20Brake%20Kit\u0026amp;flange=Big%20Ford%20New%20Style%20-%20Rear%20Kit\u0026amp;offset=2.50\u0026amp;fitment=FDR01\"\u003eWilwood installation and compatibility information\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eBefore purchase, send PMB Performance the actual housing flange, axle offset, rotor registration and parking or hydraulic arrangement.
