Whether your truck runs an Atlas inline engine, a 5.3L V8, or a second-generation 3.6L V6, aging coil packs lead to rough idling, reduced fuel economy, and sudden misfires under load. Upgrading with reliable performance ignition components restores strong, consistent spark across all RPM ranges. To optimize overall drivability, consider pairing fresh coils with a calibrated performance tune for Chevrolet or high-flow cold air intakes compatible with Chevrolet.
Our current catalog covers select applications across the 2004–2021 model years. Available fitments include the 2.8L and 2.9L four-cylinders, 3.5L and 3.7L inline-fives, the 2009–2012 5.3L V8, plus second-generation 2.5L four-cylinder and 3.6L V6 trucks.

Yes. If the code is triggered by heat breakdown, carbon tracking, or failing internal windings, installing new direct-fit coil packs will stabilize spark output and clear cylinder-specific misfire trouble codes.
Old spark plugs develop widened electrode gaps over time. This increased resistance forces the ignition coil to run significantly hotter, speeding up internal failure. Installing matched iridium spark plugs protects your new coils and delivers balanced cylinder combustion.
Yes. Each unit is engineered to match factory mounting locations, resistance specifications, and wire harness plugs for quick, bolt-on replacement on 2.8L, 2.9L, 3.5L, and 3.7L engines without modifications.
