High Performance Ignition Coil for Chevrolet LCF 3500 (2016-2018) 6.0L

High Output UF414 Ignition Coils for 2016-2018 Chevrolet LCF 3500 (L96 / LCF Platform)

Direct-fit UF414 coil pack upgrade designed to resolve ignition breakdown and misfire issues under heavy commercial loads.

The Stock LCF 3500 Ignition Shortcoming

The OEM ignition coils on the 6.0L L96 V8 are highly susceptible to thermal degradation and voltage leak when subjected to the extended duty cycles typical of Low Cab Forward commercial applications. Over time, the constant heat soak from the confined engine bay deteriorates the factory epoxy potting and internal primary windings. This thermal stress leads to increased electrical resistance, weak spark propagation, and eventual spark blowout under heavy towing conditions. Drivers experience this as intermittent hesitations, rough idling, increased fuel consumption, or cylinder misfire codes (P0300 series) when pulling payloads up steep grades.

The Engineering Solution

These upgraded UF414 ignition coils are engineered to exceed factory output parameters, providing a denser spark across the entire RPM range. By utilizing high-conductivity copper internal windings and upgraded magnetic steel cores, these coils increase secondary voltage output. The housings are molded from high-dielectric epoxy and advanced thermal-resistant polymers, which mitigate heat soak and prevent the micro-cracking that plagues the OEM units. This enhanced thermal stability ensures maximum ignition voltage reaches the spark plugs, translating to a more complete combustion event. For the technician, this means a direct plug-and-play installation that restores pulling power and prevents load-induced misfires on the commercial route.
