Sierra 18-5404-1 Distributor Rotor for Ford & GM V-8 Engines with Mallory Conventional Ignition

The Sierra 18-5404-1 is a machined distributor rotor built for Ford and GM V-8 engines equipped with Mallory Conventional Ignition, including all Mallory distributors dated 1998 and below. It mounts in the rear position of the distributor and is engineered as a direct-fit replacement rotor that meets or exceeds the performance of the original equipment part it replaces. The rotor works alongside a matching cap and condenser as part of a complete inboard tune-up lineup, helping restore accurate spark distribution and consistent ignition timing across the RPM range.

Compact and precisely machined to 0.39 x 0.39 x 0.39 inches, the 18-5404-1 is designed for durability under the heat and vibration typical of marine inboard engine compartments. It cross-references to a wide range of OEM and aftermarket part numbers, making it a straightforward replacement for boat owners servicing Chris-Craft, Chrysler, Crusader, Evinrude/Johnson, Mercruiser, OMC, and Pleasurecraft inboard ignition systems that share the same Mallory Conventional Ignition architecture.
