{"product_id":"wilwood-140-17873-d","title":"Wilwood XRD Single-Caliper Rear Drag Brake Kit, 11.25-Inch Super Alloy Rotors, Big Ford New Style 2.50-Inch Offset","description":"\u003cp\u003eBuild rear drag brakes around a Big Ford New Style flange and 2.50-inch offset. Single XRD calipers work with 11.25-inch dynamic Super Alloy rotors. 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\u003eBracket-to-caliper mounting: Lug\u003c\/li\u003e\n\u003cli\u003ePad compound selection: BP-28\u003c\/li\u003e\n\u003cli\u003eCaliper piston specification: Stainless\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eBrake-rotor package: 11.25 × 0.35 inches; Super Alloy; Drilled\u003c\/li\u003e\n\u003cli\u003eWheel-diameter reference: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eAxle-end requirement: Big Ford New Style; measured axle offset 2.50 in\u003c\/li\u003e\n\u003cli\u003eRetained-axle rotor mounting pattern: 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\u003eFlexline supply: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eInstallation hardware: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eItems not supplied: spindles, wheel hubs, master cylinder, brake booster\u003c\/li\u003e\n\u003cli\u003eWilwood part number: 140-17873-D\u003c\/li\u003e\n\u003cli\u003eConversion type: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eCaliper configuration: Forged XRD Lug Mount; 4 pistons per caliper; Type III Anodize\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSelect this rear drag-racing kit by the Big Ford New Style flange and measured 2.50-inch axle offset. One four-piston XRD caliper mounts at each rear rotor; match the bearing retainers and bracket bolt centers. The dynamic lug-drive hats retain the drilled Super Alloy rotors with internal snap rings, allowing the rotor and hat to expand separately. Hat drillings do not alter the axle wheel pattern. Provide hydraulic flexlines separately and use the exact wheel-clearance drawing. Vehicle names in the table below (Town Car) do not establish the installed rear housing; confirm the axle measurements individually.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17873-D\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1606.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%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.
