Holley Performance Products anchors the North American aftermarket through dedicated racing and street-performance distribution channels. COMP Performance Group differentiates via specialized reluctor wheel geometries for small-block and LS engine architectures.

An automotive crank trigger is a position-sensing device that detects crankshaft angular velocity and top-dead-center reference points, typically employing variable reluctance, Hall-effect, or optical detection principles with air gaps specified between 0.25 mm and 1.5 mm depending on target wheel geometry. Its primary function is to deliver phase-accurate timing signals to engine control modules, enabling precise fuel injection sequencing, ignition coil firing, and misfire diagnostics across internal combustion architectures. Magnetic sensors dominate OEM volume programs due to thermal resilience beyond 150°C operating environments, while optical variants retain niche placement in racing applications where absolute positional accuracy outweighs contamination vulnerability. Digital signal conditioning technology is displacing analog front-end designs as automakers mandate SENT protocol outputs for improved noise immunity and diagnostic depth.
