{"product_id":"wilwood-140-17884-d","title":"Wilwood Rear Dual-Caliper XRD Drag Kit, M-W\/Lamb Axle Interface, Large Studs and Drilled Super Alloy Rotors","description":"\u003cp\u003eThe M-W\/Lamb large-stud rear kit uses dual XRD calipers and drilled lug-drive rotors. Confirm 11\/16-inch studs and the 2.81-inch housing offset. The wheel-end assembly is selected by its measured housing-end interface and racing hydraulic arrangement. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems along with calipers, rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications each call for components matched to the overall braking arrangement.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWheel envelope: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eRear housing interface: Symmetrical End; measured axle offset 2.81 in\u003c\/li\u003e\n\u003cli\u003eRotor hat bolt-circle specification: 5 x 5.00; 5 x 4.75 inches; this does not change the retained hub or axle wheel pattern\u003c\/li\u003e\n\u003cli\u003eAxle stud requirement: 11\/16-inch diameter, as specified in the exact installation instructions\u003c\/li\u003e\n\u003cli\u003eHydraulic hose selection: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eHardware provision: 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 identification: 140-17884-D\u003c\/li\u003e\n\u003cli\u003eApplication and supplied quantity: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eHydraulic service-caliper specification: Forged XRD Lug Mount; 4 pistons per caliper; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eCaliper attachment: Lug\u003c\/li\u003e\n\u003cli\u003eBrake pads supplied: BP-28\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003eService-caliper port: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor assembly specification: 11.25 × 0.35 inches; Super Alloy; Drilled\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe large-stud M-W\/Lamb rear package combines dual XRD calipers with drilled Super Alloy rotors and dynamic lug-drive hats. Verify the symmetrical housing-end dimensions, 11\/16-inch studs and 2.81-inch axle offset against DS-1611. Each rotor requires clearance for two calipers and their plumbing, and the 11.25-inch nominal rotor diameter alone does not prove wheel fit. Snap rings retain the rotor in its hat, allowing separate thermal movement; hat drilling leaves the axle wheel pattern unchanged. Provide the hydraulic flexlines separately and confirm the bracket and bearing-retainer arrangement on the actual racing axle.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17884-D\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1611.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=Symmetrical%20End%20-%20Rear%20Kit\u0026amp;offset=2.81\u0026amp;fitment=AFR01\"\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.
