It is a C1500 axle conversion with separate electric parking calipers, not simply a replacement pair of factory rear calipers. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. It designs and manufactures disc brake components and complete systems, from calipers and brake rotors to valves, master cylinders, fittings and brake lines. Motorsport, street-performance and specialized installations each require those components to be matched to the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-18046-D\u003c\/li\u003e\n\u003cli\u003eRotor specification: Spec-37 Iron, SRP Drilled \u0026amp; Slotted, vented; 14.00 x 1.10 inches\u003c\/li\u003e\n\u003cli\u003eCaliper specification: 4-piston AERO4 in Black Powder Coat; radial mount\u003c\/li\u003e\n\u003cli\u003eIncluded service pad compound: BP-10; 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 5 in; 5 x 127 mm; match the installed hub\/axle pattern\u003c\/li\u003e\n\u003cli\u003eHousing\/flange application: 88-98 C1500\u003c\/li\u003e\n\u003cli\u003eRequired axle offset: 3.25 in; 82.55 mm\u003c\/li\u003e\n\u003cli\u003eParking equipment: separate electric calipers, controller and harness included\u003c\/li\u003e\n\u003cli\u003eHydraulic brake hoses: not included; select the correct application-specific lines\/fittings\u003c\/li\u003e\n\u003cli\u003eWheel clearance: 18-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\u003eUse on the specified 1988–1998 Chevrolet\/GMC C1500 rear axle configurations, following every brake-option and spindle qualification in the table.
