FAQ
How do I confirm my truck is “late 5.9” (2004.5–2007)?Check the engine data tag or calibration; late-style 5.9L began mid-2004 (“325 HP” rating). If your 2004 build is early-style, this set will not apply.
Do I need supporting fuel system upgrades?Yes. At 300% over, plan for a higher-capacity lift pump, filtration, and a stroker or dual CP3 to maintain commanded rail pressure under load.
Is tuning required?Yes. Custom calibration is required to properly manage idle quality, smoke control, and power delivery with 300% injectors.
Are cores required?Yes. S&S reman programs require timely core return; a core charge may apply if cores aren’t returned within policy timelines.
Will these pass emissions testing?These are competition-level components. Verify local/state compliance before purchase and installation.
