FAQs
Will this work with stock fuel?Yes. It’s designed for stock to mild fueling upgrades and shines as a tow/daily turbo with cooler EGTs.
Do I need an HX40 downpipe on 2003–2004 trucks?Yes. The Viper 62 for 03–04 requires an HX40-style downpipe and clamp. We recommend HX40DP3.
What supporting mods are smart for towing reliability?Head studs (ARP 247-4202), a quality intake (aFe 54-10412), and intercooler/boost-tube upgrades (03–07 kits) help keep EGTs and drive pressure in check.
Is this 2004.5–2007 compatible?No. Use the later Viper 62 for 2004.5–2007 (different downpipe requirement). This listing is for 2003–2004 only.
