{"product_id":"wilwood-140-16166-r","title":"Wilwood Rear 14-Inch GT Conversion with Red Superlite and EPB Calipers, Chevy 12-Bolt Axles with C-Clips and 2.75-Inch Offset","description":"\u003cp\u003eRed Superlite hydraulic calipers and undrilled GT-slotted 14-inch rotors provide the service braking in this rear kit. Independent red EPB calipers supply parking hold, with the mechanical package matched to the Chevy 12-bolt C-clip axle interface. Wilwood Engineering began in 1977 under founder Bill Wood and is based in Camarillo, California. It designs and manufactures disc braking equipment for motorsport, specialized applications and street-performance vehicles. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form part of the range and must match the requirements of the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number\u003c\/strong\u003e: 140-16166-R; supplied as one rear axle brake kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hats\u003c\/strong\u003e: Aluminum; Black E-Coat; hat offset 2.035 inches.

Wheel-stud pattern and register dimensions must match the supplied rotors or hats, and the parking motors and harness connectors need clearance throughout suspension travel. Compare the intended 18-inch or larger wheel with the installation drawing. Confirm C-clip axle retention and end play; a C-clip eliminator or different housing flange requires its own fit assessment.\u003c\/p\u003e\u003cp\u003eThe fitment table below is subject to physical axle-interface confirmation. Check housing flange, bearing arrangement, offset, wheel-stud pattern and center register before ordering. For Chevelle, 442, Beaumont, Camaro and Apollo vehicles, establish rear-axle fit independently of the front spindle configuration. Confirm the housing flange, axle retention and offset on the installed rear assembly.\u003c\/p\u003e\u003cp\u003eTwo dedicated motorized calipers provide parking hold separately from the hydraulic service calipers. The kit supplies their switch with pigtail, control unit and universal wiring harness. DS1353 covers the required 12V vehicle connections and component placement.
