{"product_id":"wilwood-140-7144","title":"Wilwood Mopar\/Dana Snap-Ring Rear Parking Kit — 12.19-inch Plain Rotors, Black Dynalite, 2.36-inch Offset","description":"\u003cp\u003eSnap-ring axle bearings are part of the required Mopar\/Dana mounting arrangement. This Forged Dynalite rear disc and parking-brake kit combines black powder-coated 4-piston calipers and 12.19-inch plain-face rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7144.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.\u003c\/li\u003e\n\u003cli\u003eRotor construction: Iron; vented; Plain Face friction surface.\u003c\/li\u003e\n\u003cli\u003eCalipers: 4 pistons; forged aluminum; stainless steel pistons.\u003c\/li\u003e\n\u003cli\u003eCaliper attachment: lug mount; 1\/8-27 NPT hydraulic inlet.\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Black Powder Coat.\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\u003eRotor\/hat stud-hole clearance diameters: 0.52 in; 13.21 mm.

The bearing requirement is essential; a differential name is not a substitute for checking axle retention. Use DS424 to compare the end, bearing and bracket stack before ordering. No vehicle-model fitment is implied for every axle carrying these differential names. Unlike a rear-disc package without a parking mechanism, this kit incorporates drum sections and internal mechanical shoes for that function. A cable installation must still be planned and checked for full release as well as holding operation. Hydraulic hose routing, wheel clearance and compatibility with the vehicle’s master cylinder remain part of the complete brake conversion.\u003c\/p\u003e\u003cp\u003eUse the wheel-clearance drawing in the installation instructions before purchase. The catalog minimum diameter is a guide; barrel shape, spoke clearance and wheel offset still determine fit.\u003c\/p\u003e\u003ch3\u003ePackage and installation requirements\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe one-piece iron drum\/rotors incorporate the parking-brake drums; the internal shoes provide a mechanical parking brake independently of the four-piston service calipers.\u003c\/li\u003e\n\u003cli\u003eParking-brake cables and hydraulic brake lines are separate.
