{"product_id":"wilwood-140-9222-dr","title":"Wilwood Rear Brake Kit: 12.88-inch Drilled\/Slotted Rotors for Mopar \/ Dana Rear Ends, 2.36-inch Offset and Snap-Ring Bearings, Red FNSL4R","description":"\u003cp\u003eRed powder-coated FNSL4R calipers give this snap-ring-bearing Mopar\/Dana package a visible finish distinction alongside SRP drilled and slotted rotors. Its 12.88-inch rear service brakes share the installation with an independent internal-shoe parking mechanism, requiring the correct 2.36-inch axle geometry. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood, its range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines. Component selection must account for the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\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: 1.38 \/ 1.38 in\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eKit contents and separate parts\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-9222-DR\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: Mopar\/Dana\u003c\/li\u003e\n\u003cli\u003eAxle offset: 2.36 in; 59.94 mm\u003c\/li\u003e\n\u003cli\u003eInternal drum parking-brake assemblies and bearing retainers are included; axle shafts and bearings are not supplied.\u003c\/li\u003e\n\u003c\/ul\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: SRP Drilled \u0026amp; 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; 1.540-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\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the Mopar 8-3\/4 or Dana 60 housing end and 2.36-inch axle offset before ordering. This version requires non-adjustable snap-ring Green bearings: Mopar MO400, Strange A1022 or Moser 9400M. The RP400 bearing with a pressed-on five-hole retainer is not compatible. Verify bearing diameter, flange pattern, axle register and shock clearance against DS-532; relocation of shocks may be necessary. The maximum axle flange is 6.61 inches with the specified chamfer. Hydraulic hoses, fittings and parking cables are separate; the universal 330-9371 cable kit requires application-specific installation. 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\/ds532.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.
