{"product_id":"wilwood-120-13843-bk","title":"Wilwood Black Forged Dynalite Internal Brake Caliper, 10.00–13.06-Inch Rotor Diameter","description":"\u003cp\u003eFor a brake assembly built around a nominally 0.38-inch-wide rotor, this black Wilwood Forged Dynalite Internal supplies four 1.75-inch stainless pistons in a forged aluminum body. Its 5.25-inch lug pattern locates the attachment points, while rotor offset and pad sweep determine the bracket arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.\u003c\/p\u003e\u003cp\u003eThis four-piston Dynalite uses internal fluid transfer in a spacerless body. Its 5.25-inch mounting pattern is only one compatibility dimension: rotor position, body clearance and hydraulic area also need to agree.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 120-13843-BK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Wilwood Forged Dynalite Internal; one caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston arrangement:\u003c\/strong\u003e 4 pistons; 1.75-inch bores; stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic piston area:\u003c\/strong\u003e 4.80 square inches, as specified by Wilwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad shape:\u003c\/strong\u003e Wilwood type 7112; compound selected separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e universal side configuration; Lug; 5.25-inch centers; 0.39-inch mounting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount height:\u003c\/strong\u003e 2.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor width:\u003c\/strong\u003e 0.38-inch nominal; 0.25–0.38-inch permitted range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor diameter range:\u003c\/strong\u003e 10.00–13.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid inlet:\u003c\/strong\u003e 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDust boots:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and finish:\u003c\/strong\u003e Forged aluminum; Black Powder Coat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eCheck the caliper-to-bracket attachment and rotor offset before ordering.
