{"product_id":"wilwood-140-16988-r","title":"Wilwood Rear Red Caliper and Plain Rotor Conversion for BOP 2.75-Inch Bearing Axles, Dynapro Low-Profile \/ 11 Inch","description":"\u003cp\u003eThis staggered rear brake conversion combines four-piston Dynapro Low-Profile service calipers with 11.00-inch rotors and internal drum parking-brake assemblies. The axle interface is the BOP 2.75-inch bearing flange with a 2.75-inch axle offset. Red calipers and 11.00-inch plain face rotors are the selected configuration. Based in Camarillo, California, Wilwood Engineering was established by Bill Wood in 1977. Its disc brake systems serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are matched to the requirements of the whole system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eKit supplied under manufacturer part number 140-16988-R; one listed axle\/application assembly.\u003c\/li\u003e\n\u003cli\u003eEach service caliper uses 4 stainless pistons and the Forged Dynapro Low Profile body design.

DS-1529 describes the 1964–1970 Buick\/Oldsmobile\/Pontiac axle arrangement, but no particular vehicle model is established here. Confirm the flange drawing, rotor register and axle-flange maximum of 6.61 inches with the specified chamfer. The rotor hat is drilled for 1\/2-inch wheel studs; upgrading smaller studs may require machining. Hydraulic hoses\/fittings and parking cables, hardware or adapters are not supplied.\u003c\/p\u003e\u003cp\u003ePMB Performance has 20+ years of experience with parts and fitment details.
