Match the 11\/16-inch studs and 2.81-inch offset. 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\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: Olds\/Pontiac; measured axle offset 2.81 in\u003c\/li\u003e\n\u003cli\u003eHat drilling for retained axle flange: 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\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: 140-17879-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\u003eSelect this rear drag-racing kit by the 1958–1964 Oldsmobile\/Pontiac flange and measured 2.81-inch axle offset. The required axle stud diameter is 11\/16 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. Vehicle names in the table below (Chevelle, 442, Beaumont, Camaro, Apollo) 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=140-17879-D\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1608.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=Olds\/Pontiac%20-%20Rear%20Kit\u0026amp;offset=2.81\u0026amp;fitment=GMR01\"\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.
