{"product_id":"wilwood-140-7144-dp","title":"Wilwood Polished Dynalite Mopar\/Dana Rear Kit — SRP 12.19-inch Parking Rotors, Snap-Ring Bearings","description":"\u003cp\u003eThe polished option keeps the internal-shoe parking brake while adding a bright caliper finish. For Mopar 8-3\/4 \/ Dana 60, snap-ring bearings, Wilwood specifies polished 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this rear package. Bill Wood founded Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.\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. Wilwood references universal cable kit 330-9371; installation can require cable or vehicle modifications.\u003c\/li\u003e\n\u003cli\u003eUse the non-adjustable snap-ring bearing arrangement specified by Wilwood; confirm the bearing before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSelect this rear package for Mopar 8-3\/4-inch or Dana 60 ends with the specified non-adjustable snap-ring bearings and a 2.36-inch axle offset. 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\u003eBefore ordering, compare the wheel profile with the Wilwood clearance diagram. The stated minimum size does not establish spoke or barrel clearance for every wheel of that diameter.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7144-DP.\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.
