{"product_id":"wilwood-140-14878-r","title":"Wilwood GT-Slotted Rear Parking-Brake Conversion, Red Four-Piston Calipers, Mopar\/Dana 2.36-Inch Offset and Required Snap-Ring Bearings","description":"\u003cp\u003eThe red GT-rotor version supplies Superlite service calipers, 14-inch two-piece rotors and internal parking shoes. Its housing-end mounting depends on the required snap-ring bearing, with the aluminum hat and axle offset setting the rotor position. Founded in 1977 by Bill Wood, Wilwood Engineering is now based in Camarillo, California, where its work centers on disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized installations; selecting these parts requires considering the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number — 140-14878-R.\u003c\/li\u003e\n\u003cli\u003eSupplied pad compound — BP-10.\u003c\/li\u003e\n\u003cli\u003eCaliper color, finish and hydraulic inlet — Red; Red Powder Coat; inlet 1\/8-27 NPT.\u003c\/li\u003e\n\u003cli\u003eService caliper assembly — Superlite 4R; 4 pistons in each caliper; Stainless pistons; Forged Aluminium body; Radial mounting.\u003c\/li\u003e\n\u003cli\u003eRotor construction and friction surface — Spec-37 Iron; Vented; GT Slotted; surface finish: Black Electro Coat.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions — outside diameter 14.00 in; 355.6 mm; thickness 1.10 in; 27.94 mm.\u003c\/li\u003e\n\u003cli\u003eBrake function and supply — Rear Brake Kits - Street Performance; Disc; Parking braking; rear axle; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eParking mechanism — internal parking-brake shoe assemblies included; operating cable\/clevis kit 330-9371 purchased separately.\u003c\/li\u003e\n\u003cli\u003eHydraulic package contents — brake lines included: No; master cylinder included: No; booster included: No.\u003c\/li\u003e\n\u003cli\u003eMechanical package contents — no separate hubs included; mounting hardware included: Yes; spindles included: No.\u003c\/li\u003e\n\u003cli\u003eRear flange interface — Mopar\/Dana; axle\/flange offset 2.36 in; 59.94 mm (distinct from rotor-hat offset).\u003c\/li\u003e\n\u003cli\u003eRotor mounting hat — aluminum; Black E-Coat; hat offset 1.540 in.\u003c\/li\u003e\n\u003cli\u003eNominal minimum wheel diameter — 18 in; 457.2 mm; verify full spoke and barrel clearance using the kit drawing.\u003c\/li\u003e\n\u003cli\u003eHat wheel-stud clearance diameter — 0.520 in; 13.21 mm.\u003c\/li\u003e\n\u003cli\u003eWheel bolt circle — 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\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the actual axle end even if the rear housing is called Mopar 8-3\/4 or Dana 60.
