As others have said, if you order it correctly, the difference between a similarly optioned Lariat Tremor vs Non-Tremor is only $1400. When I sell the Tremor take-off parts, I will probably make a small amount of money from the Tremor package. Plus, I get to keep the LSD, the locking rear Diff, the drive modes, the fender lips and the love them or hate them Tremor stickers. (I swapped mine for all black stickers, so they look fine to me)
I ordered my 2021 Tremor and Carli 2.0 Backcountry suspension only a week apart, and the truck arrived a couple of weeks before the suspension! I went with the 2.5" lift with Add-a-Packs in the rear, Torsion Sway bar and dual steering stabilizers. There is no need for the adjustable Radius Arms unless you are buying wheels with more than 5" of offset. (Or, if you just like the look of them) My truck rides better than stock with the 37s, so it was well worth it for me.
Also, you can get a complete 17x9 wheel and 37x12.5 tire setup for less than the Innov 8s. I looked at them long and hard, but could not justify the extra cost for a "slightly" better look. (looks are subjective and they did not have an all black wheel I liked)
