Product details

This one-inch compact tandem package adds the Mopar manual-pedal pushrod to the four-bolt mounting arrangement. Its left-mounted combination valve and connecting tubes must fit the exact firewall and brake-line layout. A disc brake manufacturer based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures calipers, rotors, brake lines, fittings, valves and master cylinders for street-performance, motorsport and specialized systems. The chosen service part must agree with the complete system's connections, dimensions and operating demands.
