{"product_id":"wilwood-120-18054-bk","title":"Wilwood Narrow DynaPro Black Caliper for 0.25-Inch rotor width, 1.75-Inch Piston Bores","description":"\u003cp\u003eFour 1.75-inch stainless pistons are fitted to this black Narrow DynaPro caliper. The selected model is a thin-pad radial design for a 0.25-inch rotor width, with no external piston dust boots listed. It is suitable as a matching caliper replacement or as part of a brake conversion whose bracket, rotor and hydraulics have been selected together. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-18054-BK\u003c\/li\u003e\n\u003cli\u003eCaliper type: Narrow Dynapro Radial Mount\u003c\/li\u003e\n\u003cli\u003eConstruction: Billet Aluminium\u003c\/li\u003e\n\u003cli\u003eFinish: Black Powder Coat\u003c\/li\u003e\n\u003cli\u003ePiston bores: 1.75 \/ 1.75 inches\u003c\/li\u003e\n\u003cli\u003ePiston type: Stainless\u003c\/li\u003e\n\u003cli\u003ePiston count: 4\u003c\/li\u003e\n\u003cli\u003ePublished piston area: 4.80 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 0.25 inch\u003c\/li\u003e\n\u003cli\u003eRotor thickness limits: 0.25–0.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter limits: 10.75–12.19 inches\u003c\/li\u003e\n\u003cli\u003eMounting style: Radial\u003c\/li\u003e\n\u003cli\u003eHandedness: Not restricted to one side; correct mounting and bleed orientation required\u003c\/li\u003e\n\u003cli\u003eMounting centers: 4.75 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole size: 0.39 inch\u003c\/li\u003e\n\u003cli\u003eMount height: 1.61 inch\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: M10 x 1.25\u003c\/li\u003e\n\u003cli\u003eRequired pad shape: 7812\u003c\/li\u003e\n\u003cli\u003ePublished pad area: 6.36 square inches\u003c\/li\u003e\n\u003cli\u003ePublished pad volume: 2.1 cubic inches\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed component weight: 3.6 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck radial stud spacing, body height and the rotor centerline before installation. In a system using a smaller-bore caliper, the larger piston area changes hydraulic requirements and should not be treated as a cosmetic substitution. The wheel must clear the entire body and hose connection, while the pad must remain fully supported on the rotor friction surface.\u003c\/p\u003e\u003cp\u003eFor help identifying the correct brake component, provide the caliper markings and installation dimensions.
