Bilstein Level Installed - Issue

Hey all - I installed some Bilstein 5100 struts along with Zone UCA and Bilstein rear shocks on my 20 4x4. Love the firmed up ride and the look of the 275/70-18 General Grabber ATX's. Trouble is, when the suspension tops out over large bumps there's a clunk from the drivers side. Have read all kinds of posts about checking top hat torque and placement of the strut washer. Top hats are tight and my kit didn't come with the washer below the spring hat and it's not noted on the instructions for the 19-20 kit. Is that right ? Have taken apart and all looks good, everything is tight. Has anyone had issues with running the Zone upper control arms with only a 2" lift? I set the struts to position 5. Only thing I can think of at this point is something is off with the control arms. About ready to take these off and go the coilover route, the clunk is driving me nuts.

Sorry I can't help, but if you're you pleased with the ride and you think it's the control arm, why not swap the stock ones back on and see if the noise is still there. If it's gone...it was a control arm issue. If still there, then it's strut related.

It seems to be loosening up over time and feeling better but it still clunks everytime the suspension tops out. Fox's might be in my future.

Did you get this clunk figured out? I’m having the same issue.

What other brans of upper control arms would someone recommend? I was told Rough Country to replace the present plastic control arms.
Thoughts?

Rough country or Readylift are the two most popular. Just due to where I live I'd opt for the Rough Country ones to avoid any rust issues.

You could go with rough country, readylift, zone, BDS or ICON. Lots of options but readylift and rough country will be the most cost effective options.

I am thinking about going with the Bilstein's (most likely all 4 if I can find them) and level the front. Sorry, but being unfamiliar with suspensions, can anyone help me understand why you replace the UCA over factory (or do you depending upon how you use the truck)? Thanks!

Nope still does it, I'm pretty sure it's the Bilsteins topping out. Super annoying.. I ordered some Fox's and will post up if that eliminates it.
Do you think the clunk is due to the zone UCA

It keeps the OEM front end geometry. Each aftermarket UCA is designed to restore the OEM geometry for a specific range of lift in the front.

The easiest way to explain it: ever see someone with the front end lifted and the wheels pointed inward at the bottom and outward at the top? They need a UCA to fix that and make the wheel vertical (OEM).

I suspect the body mount at this point, going to get under there to check it out. Have checked everything else. Getting some Fox 2.5's installed Monday, super stoked!

I installed Rough Country control arms and the 2" spacer also and in the back I went and purchased Tough Truck heavy duty springs to beef it up better., I will be removing the 2 inch spacer and installing the rough country leveling strut.

I am having my Bilstein 5100's installed next week on the front to level my truck. My 2 questions are, what clip setting should I tell them? (I'm seeing a lot of people use #5, my truck does NOT have ORP) and will I be ok just having them use the stock UCA and new ones aren't needed?

Replacing the UCA's is really just a peace of mind kind of thing. If you don't off road your truck often and you go with setting #5 on the bilsteins you shouldn't need to replace the UCA's.

On the other hand; I have the ORP and will be putting my bilsteins at setting 5 so a total of 3" front lift (1" ORP, 2" bilstein) and I am certainly planning on replacing my UCA's with a better set.
