I've had a few different Lifted Trackers.
Calmini 3 + 3 on my Geared, Locked, 4 door with 33's and I've had a couple of them with 2" coil spacers and 2" body lift and 31's.
I'd put my 4 door up against all my Friends rigs, then IF they made whatever and I didn't, I'd remind myself how Cheap I'm into the hobby, compared to their Investment. I assure you that I can go 99.9% of the places they do.

I now prefer the 2 + 2 with 31's on OEM rims. I kinda like 'em skinny.
If you were to lock the Front or Rear and gear the T-case, you would have something similar to the old Stomper Toys. Point it and Creep over/thru/around whatever.
My 4 door was pretty much unstoppable too, but that cost a lot more to put together.
Don't be fooled by 31's, get a Quality Tire though. I REALLY Like the BFG KM2's!
Red Tracker: V6 Tracker Coils, 3" Body lift, 31" KM2's.
Green Tracker: Calmini 3 + 3, Anvil, Ford 9", Geared T-case, Locked F/R. 32's.
