Ford Distributor Dist Ford 50L Mustang8693 wModule Ford 5.0L Pro-Billet Distributor Drop-in 86-93 5.0 EFI Pro-Billet distributor 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. The Pro-Billet Distributors use a stock-style trigger pick-up to accept factory connectors. For installation, you simply remove the stock distributor and bolt the Pro-Billet MSD in place! Each model is supplied with a high-quality cap with brass terminals for full spark delivery, heavy-duty rotor and a special gear to work with factory camshafts. Each distributor starts as a solid billet that is secured into a state-of-the art Computer Numerical Control (CNC) machine where it is transformed into a precision housing. 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. Proprietary formulated ductile iron. Melonite QPQ coated reduces friction and initial wear. Increased outer hardened layer thickness (RC 55-60). Micro polished surface for smooth contact. Interstitial carbide concentration improves wear resistance and
