The new MSD cap features spark plug style terminals and is firmly screwed down to the housing.<br><br>The distributor relies on MSD's race proven magnetic pickup and precision reluctor to deliver accurate reluctor 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.<br><br>Mounted to the top of this shaft is a fully adjustable mechanical advance assembly.
