I did the Z Automotive with Tazer package and it works great. Pricey but the Tazer is useful and has some fun options. Buy the one on their site that says for 392 and it fits perfect!
Thanks for posting this. I was thinking the 392 already had a larger sway bar but yes having the rear stay flatter would make a real difference on the road. How much thicker was this than the stock one?
Maybe I can help. I sold my 2016 Raptor to my nephew and ordered a TRX from a small town dealer because they were at sticker. When I was there picking it up joked with the salesman, you don't have a Wrangler 392 do you. He asked the sales manager who checked and said there is one at the rail...
I had to remove a lot from the passenger side bracket to get it to clear. I didn't notice the head of the bolt on drivers side rubbing until I read this thread. Looks to be minimal contact so I am leaving the rubber isolation washer. It is there for a reason so I would rather not remove it.
I traded my JK on a Raptor in 2016. Sold it and recently took delivery of a Ram TRX. The dealer had a 392 available at sticker so I bought it thinking I would flip it. I absolutely love it!!! Sold the TRX instead.
