{"product_id":"wilwood-140-5746-dr","title":"Wilwood Chevrolet 12-Bolt Special Rear Disc Kit — Red Dynalite Calipers, 12.19-inch SRP Rotors","description":"\u003cp\u003eChoose the red SRP arrangement only after the fixed-bearing rear housing has been identified. For Chevrolet 12-bolt Special, 3.15-inch fixed bearing, Wilwood specifies red powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this rear package. Bill Wood founded Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.\u003c\/p\u003e\u003ch3\u003ePackage and installation requirements\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNo parking-brake mechanism is supplied.

The listed modified GM applications still require that rear axle hardware; a vehicle name or front spindle conversion does not establish rear-kit fit. Wilwood currently lists a 2.91-inch axle offset, while the DS293 instruction cover specifies 2.81 inches. Measure your axle and have Wilwood confirm the correct kit before ordering.\u003c\/p\u003e\u003cp\u003eBefore ordering, compare the wheel profile with the Wilwood clearance diagram.
