OE Applications & Fitment
- 2015–2017 Dodge Challenger SRT Hellcat
- 2015–2017 Dodge Charger SRT Hellcat
If your engine has been modified with non-OEM components (aftermarket lid, intercooler changes, unusual mounts), contact HHP with your exact combo before ordering to confirm fitment.
HHP Pro Recommendation: While this engine is OE for 2015-2017 Hellcats, the 2018+ Hellcat long block #68409362AB and Demon/Redeye long block #68436298AA may be a more attractive option for most as these motors are considered upgraded version and actually cost less.
