"DSA" Sales Code for LSD?

[flyer92]

After recently reviewing the original build sheet on my '21 2-door Sport with LSD (M220 rear diff), I noticed that it lists sales code "DSA" for the "Anti-Spin Differential Rear Axle." However, the owner's manual and every other reference I've ever seen lists "DRE/DRF" as the sales code. I'm pretty sure my LSD isn't different than anyone else's, but I haven't seen "DSA" mentioned anywhere....just has me a little curious/concerned. Has anyone else seen this or have any insight?

Update: I called Jeep Customer Care this afternoon and asked the question above. Not surprisingly, the representative just told me to "go ask the dealership." I advised that I had already done this at two dealerships, and neither could explain what DSA was. He was then able to read the sales code listed in his system, which was "DRES."

Obviously, that's also different than what's listed in the manual because it adds the "S." I suspect it just denotes a specific version of the differential in the "DRE" family, perhaps for the LSD capability, or maybe because it is installed on a Sport. Again...the representative had no idea, so I'm still wondering what's actually installed on my Jeep! Just wanted to share in case anyone is tuning in with the same issue.

@JeepCares Can you please assist?
