The included aluminum hats and drum parking mechanism support a measured 2.81-inch axle offset; hoses and cable hardware remain separate installation choices. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; its Camarillo, California operation serves motorsport, street-performance and specialized applications. Each component must be chosen for its role within the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003ch4\u003eRotors and mounting dimensions\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRotors: 12.88 in; 327.15 mm diameter x 1.10 in; 27.94 mm thick; vented Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFriction faces: GT Slotted\u003c\/li\u003e\n\u003cli\u003eRotor finish: Black Electro Coat\u003c\/li\u003e\n\u003cli\u003eInternal vanes: 48 curved\u003c\/li\u003e\n\u003cli\u003eHats: aluminum; Black E-Coat; 1.950-inch hat offset\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance patterns: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm\u003c\/li\u003e\n\u003cli\u003eHat wheel-stud clearance holes: 0.520 \/ 0.520 \/ 0.520 in, corresponding to the listed hat patterns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eKit contents and separate parts\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-9224-R\u003c\/li\u003e\n\u003cli\u003eSupply: one kit with brake components for both sides of the rear axle\u003c\/li\u003e\n\u003cli\u003eMounting hardware: included\u003c\/li\u003e\n\u003cli\u003eHubs: not included\u003c\/li\u003e\n\u003cli\u003eSpindles, master cylinder and brake booster: not included\u003c\/li\u003e\n\u003cli\u003eHydraulic hoses: not included\u003c\/li\u003e\n\u003cli\u003eRequired axle housing end: Olds\/Pontiac\u003c\/li\u003e\n\u003cli\u003eAxle offset: 2.81 in; 71.37 mm\u003c\/li\u003e\n\u003cli\u003eThe supplied internal-shoe parking brake operates independently of the four-piston service calipers.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCalipers and friction components\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCalipers: Forged Narrow Superlite 4R; 4 pistons per caliper\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Red Powder Coat\u003c\/li\u003e\n\u003cli\u003eBody construction: Forged aluminum\u003c\/li\u003e\n\u003cli\u003ePiston material: stainless\u003c\/li\u003e\n\u003cli\u003eCaliper mounting: radial\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-10\u003c\/li\u003e\n\u003cli\u003eListed piston bore sizes: 1.12 \/ 1.12 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSelection is determined by the 1958–1964 Oldsmobile\/Pontiac housing-end pattern and a measured 2.81-inch axle offset, including modified vehicles fitted with those ends. The vehicle entries in the table below do not establish stock rear-axle compatibility: a Ridetech front-spindle description does not identify the rear housing end. Verify flange, bearing, register and shock clearance using DS-534 and the axle-offset worksheet. Parking cables and hydraulic lines are purchased separately; universal cable kit 330-9371 is an application-dependent option. Nominal minimum wheel diameter: 17 in; 431.8 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.\u003c\/p\u003e\u003ch3\u003eInstallation documents\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds534.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eTechnical bulletin\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWARNING: This product can expose you to chemicals including Arsenic, Cadmium, Chromium (Hexavalent compounds), Lead, Nickel, Cobalt and Antimony Trioxide which are known to the State of California to cause cancer or other reproductive harm.
