When you start making serious power with your EFI Ford, the stock distributor shaft is one of the weak links of the engine. These Pro-Billet models answer the need for an affordable replacement in a strong and great looking package. Each distributor starts as a solid billet of 6061-T6 aluminum. This billet is then secured into a state-of-the-art Computer Numerical Control (CNC) machine where it is transformed into a precision housing with tolerances within 0.001". The base of the distributor under goes the same machining process then is assembled to create a strong housing with no porosity plus looks great! Inside each housing there is a sealed ball bearing at the top of the shaft. This design is responsible for accurately guiding the oversized polished steel shaft throughout the entire rpm range of your engine. The shaft is also QPQ coated for friction reduction and corrosion resistance. Both Pro-Billet Distributors use a stock style trigger pickup and comes with plug-in connectors. For installation, you simply remove the stock distributor and bolt the Pro-Billet MSD in place! The Distributors are supplied with a high quality cap with brass terminals for full spark delivery, heavy duty rotor and a steel gear to work with the factory roller camshafts.
