Its 4.75-inch radial mounting centers and 1.62-inch piston bores must match the brake assembly. 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\u003eThe Billet Narrow Dynalite radial caliper uses four stainless pistons, internal fluid transfer and type 7816 pads. Its 4.75-inch stud spacing differs from the 3.50-inch lug-mount Narrow Dynalite layout.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 120-15565-SI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent:\u003c\/strong\u003e Wilwood Billet Narrow Dynalite Radial; one caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody and finish:\u003c\/strong\u003e Billet aluminum; Type III anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDust boots:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston arrangement:\u003c\/strong\u003e 4 pistons; 1.62-inch bores; stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic piston area:\u003c\/strong\u003e 4.12 square inches, as specified by Wilwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e universal side configuration; Radial; 4.75-inch centers; 0.39-inch mounting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount height:\u003c\/strong\u003e 1.24 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\u003ePad shape:\u003c\/strong\u003e Wilwood types 7816 \/ 7216; compound selected separately\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor width:\u003c\/strong\u003e 0.81-inch nominal; 0.75–0.81-inch permitted range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor diameter range:\u003c\/strong\u003e 11.75–12.19 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eFor a replacement, compare the entire caliper specification rather than the finish or logo.
