{"product_id":"wilwood-140-17880-d","title":"Wilwood Dual XRD Rear Drag Brakes for Oldsmobile\/Pontiac Axle Ends, 11\/16-Inch Studs, 2.81-Inch Offset and Lug-Drive Rotors","description":"\u003cp\u003eArrange dual rear drag calipers on the specified Oldsmobile\/Pontiac flange. This large-stud XRD kit requires an 11\/16-inch stud and offset check. 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\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: 140-17880-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\u003cli\u003eWheel envelope: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eRear housing interface: Olds\/Pontiac; measured axle offset 2.81 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eFor the large-stud Oldsmobile\/Pontiac drag-racing configuration, verify an 11\/16-inch stud and 2.81-inch axle offset before purchase. The exact DS-1609 instructions specify that stud size for this dual-XRD selection. Each rear rotor has two four-piston calipers; plan their hydraulic circuits and compare both brackets with the housing end and wheel drawing. The drilled 11.25-inch Super Alloy rotor floats in a snap-ring-retained dynamic lug-drive hat, leaving the original axle wheel pattern unchanged. Hoses are separate.
