FAQs
Do I need an HX40 downpipe with this turbo?Yes-this Super PhatShaft 66 requires an HX40-style downpipe for proper fitment on 2003-2004 5.9L trucks.
Is this suitable for towing?It's built for trucks with multiple fueling upgrades. With the right tune and supporting mods, it can tow, but it's aimed at higher-power street/track builds. For frequent tow duty on mild fuel, consider a smaller PhatShaft.
What supporting mods do you recommend?Healthy lift pump/CP3, appropriate injectors, clean intercooler path, and fresh oil feed hardware. See our Recommended Parts above.
