Time for a review of mods to date, after several thousand miles of roads and trails.
The lift:
Ride quality is excellent. With the combination of lift and tires it’s comfortable on pavement and rough terrain.
Handling is decent, as long as you respect the higher COG.
Steering is precise, one of the reasons I like IFS. It is slightly sensitive due to the higher COG. The maximum cut angle on the front wheels is less than stock, so the turning circle is larger; that’s a noticeable downside in maneuvering.
Track width increases at the front using lift spindles, by about 4”. Add in the effect of big tires and the required different wheel offset to clear the spindles and it’s overall close to 8” wider at the front tires. That’s the one big downside to IFS lifted GM in my opinion. It’s noticeable on the trails as the front tires tend to snag objects at the outside edges of ruts and pull at the steering.
Wheels:
I’m about 90% satisfied with these for my purposes. Not perfect because they’re not hub centric which makes me think they might be behind a slight high speed imbalance.
Tires:
BFG FTW is all I can say. I’ve been driving around on all sorts of nasty terrain including volcanic rock, and that’s nasty sharp stuff. Quiet like highway tread on the road, grip well in the rain. Not a mud tire, if I was doing much of that I’d get the MT.
The cabinetry:

No rattles or squeaks and keeps all my gear in place through a lot of rugged trails. One of the dogs did complain that carpeting on plywood was not as soft as the rear seat cushions had been, so I had to buy her a memory foam dog bed for the rear; now she’s happy.
The stereo head unit:
This is an aggravating POS don’t buy it. Glitchy. Hard to use screen controls while driving. The sound is good, that the only good thing I can say about it.
Hopefully this long dissertation will help some future readers decide what they will or will not spend their hard earned money on.
