{"product_id":"wilwood-140-7676-dr","title":"Wilwood 12.19-inch SRP Drilled\/Slotted Dynalite Front Hub Kit, Red — 1955–1957 Chevrolet passenger cars","description":"\u003cp\u003eRed calipers are combined with SRP rotors and replacement hubs for the specified Chevrolet spindles. At the front axle, this kit pairs red powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors with the mounting hardware for 1955–1957 Chevrolet passenger cars. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications, with a range including calipers, rotors, master cylinders, valves, fittings and brake lines. Selecting the mounting and hydraulic components together is part of building the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7676-DR.\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; SRP Drilled \u0026amp; Slotted friction surface.\u003c\/li\u003e\n\u003cli\u003eWheel-size guide: 15 in; 381 mm minimum nominal diameter; verify actual template clearance.\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: Red Powder Coat.\u003c\/li\u003e\n\u003cli\u003eSupplied hub wheel bolt circles: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm.\u003c\/li\u003e\n\u003cli\u003eIncluded wheel stud thread: 1\/2-20.\u003c\/li\u003e\n\u003cli\u003eSold as one kit.

Verify the original spindle before selecting the hub kit, especially on a car that has already received a disc conversion or suspension change. New hubs supply two wheel bolt-circle options and 1\/2-20 studs; check that the intended wheels match the selected pattern. DS449 describes the bearing and hub assembly sequence and provides the clearance profile for the 12.19-inch rotor. The kit changes the hub and braking hardware but does not include replacement spindles, a booster or a master cylinder. Review those existing components as part of the finished conversion rather than treating the new calipers as a complete hydraulic system.\u003c\/p\u003e\u003cp\u003eThe listed applications below retain their equipment qualifiers.
