FAQ
Will these fit my 2001–2004 LB7?Yes. This set is built for the 2001–2004 GM Duramax 6.6L LB7 platform.
Do I need tuning and supporting mods?Yes. At 250% over flow, plan on upgraded fuel supply (lift pump/filtration), adequate turbo airflow, and custom calibration.
Are these injectors balanced and flow-matched?Yes. S&S calibrates on OE-grade equipment and matches sets for tight cylinder-to-cylinder consistency.
