{"product_id":"wilwood-140-17881-d","title":"Wilwood Rear XRD Single-Caliper Drag Brake Kit, M-W\/Lamb Axle Ends, Half-Inch Studs and 2.81-Inch Offset","description":"\u003cp\u003eM-W\/Lamb axle ends with half-inch studs use the single-XRD rear drag package. Measure the 2.81-inch offset and compare the housing-end bolt centers. The wheel-end assembly is selected by its measured housing-end interface and racing hydraulic arrangement. Camarillo, California, is home to Wilwood Engineering, the disc-brake manufacturer Bill Wood founded in 1977. Wilwood designs and manufactures systems and components including master cylinders, calipers, rotors, valves, fittings and brake lines. Those parts serve motorsport, street-performance and specialized uses and must be selected as part of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCaliper configuration: Forged XRD Lug Mount; 4 pistons per caliper; Type III Anodize\u003c\/li\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: Symmetrical End; measured axle offset 2.81 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\u003eAxle stud requirement: 1\/2-inch diameter\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: 140-17881-D\u003c\/li\u003e\n\u003cli\u003eConversion type: rear conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSelect this rear drag-racing kit by the M-W\/Lamb symmetrical housing-end flange and measured 2.81-inch axle offset. The required axle stud diameter is 1\/2 inch. 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.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-17881-D\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1610.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=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.
