{"product_id":"wilwood-140-7146-d","title":"Wilwood Black-Caliper SRP Rear Conversion — Five-Lug Ford 8.8, 12.19-inch Parking Rotors","description":"\u003cp\u003eBlack Dynalite calipers and SRP discs are configured for the 2.50-inch-offset Ford 8.8 end. The supplied black powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors are configured for Ford 8.8 five-lug, 2.50-inch offset. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. The company designs and manufactures disc brake systems and components for motorsport, street-performance and specialized vehicles. Calipers, rotors, master cylinders, valves, fittings and brake lines must be selected around the needs of the complete system.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThis conversion is arranged for the Ford 8.8-inch rear axle with five-lug wheel mounting and the specified 2.50-inch axle offset. A four-lug axle or an assembly with different shafts and offset must not be assumed compatible. Use DS426 together with the axle worksheet to identify what is actually installed. The kit combines four-piston service braking with internal shoes in the parking-brake drums; the hydraulic calipers do not perform the mechanical parking function. Provide the housing and axle measurements when requesting assistance; the installed hardware determines compatibility. Check wheel bolt-circle compatibility, parking-cable attachment and the flexline route before assembly. Each of those checks matters independently of the Ford 8.8 differential designation.\u003c\/p\u003e\u003cp\u003eCheck the actual wheel against the manufacturer template, including the inner barrel and back of the spokes. A nominal wheel diameter by itself does not guarantee clearance.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7146-D.\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.
