{"product_id":"wilwood-120-16731","title":"Wilwood TX4R Forged Radial Mount Caliper, Left Anodized, 1.25-Inch Rotor Width","description":"\u003cp\u003eWilwood supplies this left TX4R brake caliper with an anodized finish. Its 9.63-inch mounting span and 1.25-inch-wide rotor configuration are key checks when selecting a single caliper for an existing system. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among the disc brake components designed and manufactured by Wilwood Engineering. Bill Wood founded the company in 1977; it is based in Camarillo, California. The range serves motorsport, street-performance and specialized systems, with component selection determined by the full brake arrangement. The forged TX4R is a four-piston radial caliper intended for heavy vehicle brake assemblies. This exact 1.25-inch nominal-width unit differs from wider TX4R variants. Match the 10120 pad shape, bracket offset and available wheel space rather than relying on the family application summary.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16731\u003c\/li\u003e\n\u003cli\u003eComponent: TX4R Forged Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Left\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 1.17–1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 14.25–16.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 13.4 lb\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 9.63 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 3.07 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003ePistons: 4; stainless steel; bore dimensions 1.62\/1.38 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 3.56 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: Yes\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 10120; shape number does not specify a friction compound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eMatch the 9.63-inch radial attachment to the existing bracket, then check caliper centering over the 1.25-inch nominal-width rotor.
