{"product_id":"wilwood-120-13338-rd","title":"Wilwood Aero4 Red Caliper, 1.98-Sq-In Area \/ 1.12-Inch Pistons \/ 1.10-inch Rotor Width","description":"\u003cp\u003eA red powder-coated AERO4 with four equal 1.12-inch bores, this caliper has no separate left- or right-hand designation. The stainless pistons operate within a forged radial body configured for a nominally 1.10-inch-wide rotor. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering designs and manufactures disc braking systems. Its motorsport, street-performance and specialized range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected as parts of a complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-13338-RD. Component: Aero4 Radial Mount caliper.\u003c\/li\u003e\n\u003cli\u003eSupply: one brake caliper, not a complete axle brake kit.
