Ford owners with distributor clearance issues due to blowers, air cleaners, or any other parts interference will love MSD's low profile, crab cap style distributor. The use of a crab cap allows the spark plug wires to exit the side of the distributor cap significantly lowering the overall height. Ford crab cap distributors are built on the proven foundation of the MSD Pro-Billet distributor line. They rely on MSD's race proven magnetic pickup and precision reluctor to deliver accurate trigger signals to the MSD Ignition throughout high rpm. The reluctor assembly is turned by a hardened steel shaft which rides in a sealed ball bearing for high rpm stability and endurance. Mounted to the top of this shaft is a fully adjustable mechanical advance assembly.
