{"product_id":"wilwood-140-17875-d","title":"Wilwood Single XRD Rear Dynamic Drag Brake Kit for Big Ford 2.36-Inch Offset, 11.25-Inch Drilled Super Alloy Rotors","description":"\u003cp\u003eA Big Ford axle with 2.36-inch offset takes the specified single-caliper XRD rear package. Compare bearing retainers and the dynamic hat interface. 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\u003eMount arrangement: Lug\u003c\/li\u003e\n\u003cli\u003eSupplied brake-pad material: BP-28\u003c\/li\u003e\n\u003cli\u003eCaliper piston construction: Stainless\u003c\/li\u003e\n\u003cli\u003eCaliper fluid connection: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor diameter, width, material and face: 11.25 × 0.35 inches; Super Alloy; Drilled\u003c\/li\u003e\n\u003cli\u003eNominal wheel diameter starting point: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eHousing-end flange and axle relationship: Big Ford; measured axle offset 2.36 in\u003c\/li\u003e\n\u003cli\u003eHat drilling for retained axle flange: 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\u003eBrake-hose provision: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eSupplied installation fasteners: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eComponents outside the kit: spindles, wheel hubs, master cylinder, brake booster\u003c\/li\u003e\n\u003cli\u003eWilwood manufacturer number: 140-17875-D\u003c\/li\u003e\n\u003cli\u003eKit function and position: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eCaliper family, piston count and finish: 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\u003eThe single-caliper XRD arrangement is built for the documented Big Ford housing end with 2.36-inch axle offset. Inspect the actual axle flange, bearing retainer and bracket centers against DS-1606 before ordering. Each rear wheel uses one four-piston caliper on an 11.25 × 0.35-inch drilled Super Alloy rotor. The lug-drive hat is retained by an internal snap ring and allows independent rotor expansion; it does not alter the axle wheel-stud pattern. Confirm wheel space and supply the hydraulic hoses separately. The preserved Lincoln Town Car row below requires axle verification and cannot establish fit from model year alone.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17875-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%20-%20Rear%20Kit\u0026amp;offset=2.36\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.
