Show original supplier description

This billet distributor features a Hall Effect crank trigger sensor, ensuring a noise-free RPM signal to the Sniper ECU for precise operation. Its durable billet housing offers excellent corrosion resistance and a premium aesthetic. The patented Clear Installation cap simplifies the installation process, eliminating confusion. For decades of reliable accuracy, the distributor's shutter wheel is pinned and welded to the shaft. This unit comes with a cast gear installed; however, it is recommended to consult your camshaft manufacturer for the appropriate gear material for your specific application. Note that the Hyperspark CD Ignition Box (12A119-2HS) and Ignition Coil (12029-6HS) are sold separately but are required for a complete system. The distributor includes a wire retainer for a clean installation. Applications include Ford 351W engines. Please be aware that this product is C.A.R.B. designated as not 50-state legal for all year, make, model, and engine combinations.
