{"product_id":"wilwood-120-15374","title":"Wilwood Dynapro Narrow 4-Piston Caliper in Type III Anodized, 5.25-Inch Lug Attachment","description":"\u003cp\u003eThe Narrow Lug Mount Dynapro is shaped around a reduced outboard profile, making rotor-hat and wheel clearance central to component selection. Four equal 1.75-inch stainless pistons provide 4.80 square inches of hydraulic area in this Type III anodized, forged caliper. It uses a nominal 0.38-inch rotor-width channel and a 5.25-inch lug pattern, rather than a vehicle-specific conversion supplied as a complete kit. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.\u003c\/p\u003e\u003cp\u003eThis narrower-outboard-profile Dynapro uses four pistons with a 5.25-inch lug pattern. Top-access type 7812 pads and internal fluid passages support service, but the reduced profile must be checked against the actual wheel and rotor-hat dimensions.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 120-15374\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Wilwood Dynapro Narrow Lug Mount; one caliper\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\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\u003eRotor width:\u003c\/strong\u003e 0.38-inch nominal; 0.31–0.42-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\u003ePad shape:\u003c\/strong\u003e Wilwood type 7812; compound selected separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and finish:\u003c\/strong\u003e Forged aluminum; Type III anodized\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\u003eMount height:\u003c\/strong\u003e 2.10 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eMeasure the available space beside the rotor hat and compare it with the caliper drawing; the narrow body does not guarantee wheel clearance. This version requires a rotor within the listed 0.31–0.42-inch width and 10.00–13.06-inch diameter ranges, together with correct 5.25-inch lug spacing and mounting offset. Check pad sweep, the 1\/8-27 NPT hose connection and the required piston area before substituting it for another Dynapro.\u003c\/p\u003e\u003cp\u003eThis listing covers one caliper.
