Distributor Cap, MSD, GM HEI, Replacement

MSD engineers created this ignition system to be capable of running above 9,000 rpm, which is 50% more current than stock units that lose spark energy at approximately 4,500 rpm. This unit also delivers a much more precise timing signal. Features include a magnetic pickup, billet reluctor, Tuftride-coated shaft that is guided by a sealed ball bearing and long sintered bushing, adjustable mechanical advance assembly all of which is enclosed in a billet aluminum housing that is CNC-machined. This is a complete set up, ready to drop in.
