{"product_id":"wilwood-140-18123-r","title":"Wilwood Front GT-Slotted Brake Kit — GM C10-Family Aluminum ProSpindles (1963–1987), Red 16-Inch TX6R","description":"\u003cp\u003eFor a C10-family project already using Wilwood Aluminum Modular ProSpindles, this red TX6R kit supplies 16-inch GT-slotted front brakes. The original-spindle installation is excluded, and the wheel-offset change differs between the early and later applications. Wilwood Engineering’s disc brake systems and components serve motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977; it is based in Camarillo, California. Wilwood designs and manufactures brake rotors and calipers as well as master cylinders, valves, brake lines and fittings. Selecting compatible components is essential to the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18123-R\u003c\/li\u003e\n\u003cli\u003eRotor specification: Spec-37 Iron, GT Slotted, vented; 16.00 x 1.38 inches\u003c\/li\u003e\n\u003cli\u003eCaliper specification: 6-piston TX6R in Red Powder Coat; radial mount\u003c\/li\u003e\n\u003cli\u003eIncluded service pad compound: BP-22; Stainless pistons\u003c\/li\u003e\n\u003cli\u003eCaliper body material: Forged aluminum\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance pattern(s): 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm; 5 x 5.5 in; 5 x 139.7 mm; match the installed hub\/axle pattern\u003c\/li\u003e\n\u003cli\u003eHydraulic brake hoses: not included; select the correct application-specific lines\/fittings\u003c\/li\u003e\n\u003cli\u003eWheel clearance: 20-inch wheels may fit; verify the manufacturer’s complete caliper\/rotor template for the installed wheel\u003c\/li\u003e\n\u003cli\u003eSupplied as one kit with mounting hardware; spindles, hubs, master cylinder and booster are not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eRequires Wilwood C10 Aluminum Modular Pro Drop Spindles and the listed five-lug configuration.
