At face value, that solution sounds fantastic, and one I would highly consider.
When did this upgraded package become available, at PRI/Sema?
This package would IMO be a great solution for Reilly IFS users that want a beefier hub set-up for heavy car RB or track day cars and or a 2" drop option.
What does concern me, the $649 price mentioned on the video sounds too good to be true.
Understand there are no corvette style HD hubs manufactured with 5x4.5" BC, if you look closely at the video you will spot a relief cut into the hub to allow the Mopar BC studs to be installed.
How much that machined cut weakens the bearing carrier concerns me.
Additionally, the C7 sealed hub assemblies based on internet reports are a wearable/replaceable item with a fixed life in hard cornering situations.
I really would have liked to have seen an Alum upright that C7's have.
No matter what, it's progress.
