MSD Pro-Billet Front Drive Distributors

MSD's Pro-Billet front drive distributors are the solution for race engines that don't have room for a standard distributor, due to firewall clearance or intake combinations. They're run by a wide 9mm belt that is driven by a pulley installed on the camshaft. The belt is wider than any other drive assembly for increased strength and durability. The distributor head is CNC-machined from billet aluminum and is secured to a stout billet aluminum bracket for strength. This system is an extremely accurate way to distribute the spark energy in harsh racing conditions. The distributors have a built-in belt adjustment feature for easy tension adjustments, and a band clamp mount for easy rotor phasing adjustments. They include MSD's Pro-Cap that is injection-molded from Dupont Rynite material for high dielectric strength, and the five in. diameter ensures accurate spark delivery. The distributors are supplied with mounting bolts, a cam pulley, hardware, and a drive belt. They must be used with a Jesel camshaft belt drive kit and an MSD Flying Magnet crank trigger.
