If it's happening without the sway bar i'll look into the strut setting.
From the pics you posted it seems you're using the 4th notch so that should be 1.2"
How is the spacer situation setup in your case, Do you have a top spacer only ? or top spacer + preload spacer ? what's the size on the spacers ?
Have you done the droop test per post#9 ? Curious to see how much can you droop and what's the angle on your UCA's and CV axels when the wheels are in the air.
Just the top spacer, no preload. It's the BDS 4" kit spacer, same height as the RC one I had replaced with it.
See Post #25 for droop test, roughly 3.5" droop, both tires off the ground. BJ angles didn't look too bad and I didn't think to get a CV pic. I will though, but they didn't look too bad either, nothing appeared to be binding.
I second the droop test to see what you got. The BDS 4” kits want the struts to be turned 180 degrees not the case on the 6” so with the 4” there is not much wiggle room with the geometry. The problem is it’s an older kit and really has to be diagnosed one part at a time. Is it not bad on big bumps but small bumps feel like you have a solid suspension?(meaning small bumps feel exaggerated and like someone kit the front bumper with a bat)
I hear ya. Really wish there were good dedicated suspension shops around here. You're spot on with the small bumps, but it's bad on big dips and bumps as well. Not so bad with the sway bar on though. It was ok all around after changing upper control arms and having wheel alignment. Then literally the next day it was like a different truck again. That's the part I can't explain.

My level just showed up. I forgot about the leveling kits not being true to size. The 2" only measures just about 1 1/4" so not even sure if any point to use? Unless I max the Bils to 2.8?
I also just decided to measure all four corners since it's been a while and my pass side is sitting about 1 1/4" higher. That's strange. Last time I measured both sides were within 1/4". So right now front pass side actually sits higher than the rear.

That's because our IFS motion ratio. it's 1.6:1 more or less, so 1.25x1.6=2" height.

What are your plans for the level

As Hodge suggested, I'm thinking of swapping out the 4" strut spacers with the level and raising the Bils from 1.2 to max. to possibly eliminate the struts being the cause, as I'm only getting about 1.5" of down travel before hitting the bump stops.

So it's worse with the sway bar off. And now you're leaning 1.25"? Is that with sway bar connected?

Don't mind the overall height of the spacer it's self, just honor the lift height it's advertised for and offset that with the preload in the 6112s. Same theory as the ready lift 4" kits, except you have differential drops.

I still feel like stuffing a 4" tall spacer above a stock strut just has **** jammed up in there, to me none of this makes sense but something has your geometry wadded up pretty bad.

You’d be a lot better off lowering the bills to the first notch and using the current spacer

@smoothee measure your current top hat spacer and let me know what it is. Then post your measurements in all 4 corners

Just to clarify, my logic behind this was it seems he is running minimal up travel currently. Iirc the 6112s are a small amount longer in compression than stock, but not by much. With him having 3.5" down travel that leaves something like 2-2.5" of compression, taking into account the big bump stop on the shaft and that's like 1"-1.5" of compression before he's in the bump zone. The pictures really don't show much out of the ordinary compared to what you or jb1 posted in the past, heck you had like 8" of lift with that eibach combo for a bit and were stoked on ride quality. You cant revert back to stock after installing these kits either....corrext?

Again this was just a theory, I don't and have never had a drop bracket lift so I have ZERO to compare to. It just seems awfully see if that the change to 6112s started a whirl wind of nonsense. Having bump steer type issues in an IFS truck has me scratching my head.

I get it and see where you’re coming from. But removing some preload from the 6112’s are going to soften the ride. Also the 6112’s could have had a bad seal and blew out pre mature (easily missed with the suspension not kept clean)
