Hellcat Supercharger Belt confusing. Which belt do I use?

Hellcat Supercharger Belt confusing.  Which belt do I use?

We receive quite a few emails and messages requesting Supercharger belt sizing on their Hellcat vehicle.  We always recommend one of our belt tensioners, which helps with belt stretch or if you tend to swap pulley's here and there.   

Below are some recommended belts for each upper/lower pulley configuration.  It's still a work in progress, so check back for more info.  Please email us if you're using another belt brand or combination that works well.
