FAQ
What does “2nd-gen style” mean on a 2003–2007 truck?It centers the turbo on a T4 manifold (like 1994–2002 trucks) for improved flow and serviceability on 03–07 5.9L platforms.
How does the .91 A/R 63/68 combo drive?It balances spool and top-end on the 5.9L. Expect quicker response than larger A/Rs while supporting healthy power and towing.
Is an HX40 downpipe included?Yes — the kit includes a high-flow HX40 downpipe to mate the turbo outlet to your exhaust.
Do I need studs and an A/C reroute?Head studs are recommended for sustained boost and heat. An A/C reroute and proper oil feed help ensure clean, reliable installation.
