Overview

Compu-Fire Stators

Compu-Fire stators are high-output electrical replacement and performance rotor components. They're primarily designed for 1980s-and-up Harley-Davidson© Big Twin (Evolution and Twin Cam) motorcycles to generate electrical power for the charging system.

What they do:

* Power generation: Stators work inside the engine's primary case as part of the alternator/charging system to convert mechanical energy into AC electrical power
* High output: Unlike standard OEM stators, Compu-Fire options—such as their 32-amp and 40-amp 3-phase systems—deliver increased and more reliable electrical current
* Narrow profile design: Many Compu-Fire stators feature a unique narrow profile built to fit cleanly inside stock or custom Softail, Dyna, and FLT primary cases without needing frame or case modifications
* Heat management: They're often paired with specialized low-drag or series-type voltage regulators and vented rotors to reduce engine drag, lower operating temperatures, and handle heavy electrical loads from fuel injection or aftermarket accessories
* Common models and types:
-- 55404 (40 amp 3-Phase): Built for 1981-99 Harley© Evolution Big Twin models
-- 55405 (40 amp 3-Phase): Built for Twin Cam engines
-- 55530 (32 amp): A direct replacement style 32-amp stator for 1981-99 Evo and aftermarket Big Twin models
-- 55534 (32 amp): Fits carbureted models only, including 1999-2003 Harley-Davidson© models
