I will be the oddball of the group and suggest leveling it. Or as jwc suggested mod the fenders to fit 35’s. In my experience a congito to lift is not worth extra the cost over other lifts. It is lacking in brackets for brake lines and sensors to justify the premium price.

I noticed no difference in ride from going from a leveled truck to a 4” lifted. Yes the suspension angles are now flat, but I suspect the truck will rot away prior to seeing a “pay back” on replacing wheel bearings and steering gear vs the lift cost.

For mine it was like night to day difference from leveled to lifted.
My body getting beat up when leveled along my wife bitching all the time riding in my leveled truck was well worth the cost for the lift.

I even went on a test drive after mine was lifted on a new 2013 GMC Dmax 3500 SRW comparable to mine except with stock suspension, mine lifted 4” (only on the front) the ride on mine was better and smoother.

The one part about Cognito that very few consider or even know about is Cognito’s lift is made/machined out of solid metal stock, not cast in place like most of the other lower priced lift kits.

I mean I have had a lifted truck and really never paid attention to the ride. I had a Toyota Tundra with 6inch RCD lift with 35inch nitto mud grapplers. They hummed everywhere lol. But you guys are all over the place with your opinions, so it’s hard to make up my mind lol

Both my '15 and '17 had/have a kryptonite leveling kit, but both trucks ran aftermarket wheels. On my '15 I ran fuel 20x9 +20 offset and my '17 I am running 20x9" +12 offset. Extreme customs fit 295/55/20 (Nitto MTs which spec out to 32.91"x12.52" per nitto) on a fuel 20x9" +20 offset with no leveling kit
With that said I would bet I could get them to rub seeing how close they were in the video.

Everyone has their own opinion, you gots to remember we’re talking about 2500 - 3500 rougher riding trucks in the first place.
Weighing 7500-8100 lbs standing alone all by themselves, mine weighs 8100 dry.
I doubt the Toyota you had fits in these specs.

Stock suspension would be about the best ride, leveled cranking the keys you stiffen up the ride along with less front end travel.
The UCA’s alone help a little but you still
have less travel and a stiffer ride.

Lifting you gain back the travel and have the stock ride back, only a little higher.

You have to explain how you loose travel with aftermarket UCAs(as long as you don't over crank.) If thats the case if you decide to run the Cognito kit above 4" you will loose travel then? My last truck the ride did firm up some but I went much higher than I did in my '17. I only cranked my '17 1.5" above factory and I could of got away with that without UCAs but I do feel they give enough benefits to offset the cost. Anyway, the ride in my '17 is no different than factory. I have ran trucks with lifts (CST6-8", Cognito 4-6", and a couple others on none duramax trucks) and I will say if you don't go above ~2" on a level with UCAs and aftermarket shocks the truck rides great.

Really,
When you crank up the keys you loose travel,
any cranking you do you loose travel.
Add Cognito UCA’s the ONLY thing that’s changed is the ball joint angle it will be more level instead of a big drop angle which is easier on the ball joints but you still lost the travel.

For the ride to be decent you need at least 1” min. travel between the bump stop and cushion, I have about 1 1/4”.
Any cranking you loose clearance, I had about 7/16” before I installed my Cognito UCA I ended up with 1/2”, not enough.
Trust me I’ve done/tried everything to save a $ before I saw the light and lifted.

Good by

Do you have any pics of your leveled '17?
