Last month I installed the Thuren 1/2" springs, track bar and Thuren/Fox IFP 2.0 shocks on my 2022 3500. During the install, when installing the front shocks, I noticed I ran out of threads on the stem of the upper shock mount. The connection was mostly tight, but sure enough, on the first drive I had a clunk coming from both front shocks. I contacted CJC Offroad, who reffered the issue to Thuren. I figured they sent the wrong bushings. Thuren's fix was to send me 4 washers. Has anybody else had this problem or noticed something similar with the Fox shocks? Seems like a cheap and sloppy fix for upgraded suspension pieces.

That's funny - I had the same thing happen to me. I did the same fix that Thuren sent you. Just stacked some washers between the nut and the hat for the bushing.
I put the same shocks on my father's 2500. Compared the two and they just didn't run the threads far enough down. His did not have this problem.
Doesn't really bother me that it's a "cheap" fix. It's been working great for at least 12k miles for me. You'll never see it anyways.

Im just curious how long ago did you take delivery of the shocks? I got a kit in a few weeks ago, I’ll take a look at the threads when I get home from vacation to see if they didn’t run the die all the way down mine either. Can save me a little time not needing to bolt it up 2x.
I installed the same shock set up on my 2022 Ram 2500 last fall. Light miles this winter but just taking a trip to Utah and developed a significantly loud noise on washboard road. Turns out the driver's side top rubber bushings are destroyed. This with less than 4000 miles on the new set up with about 40 miles of modest bumpy desert road that rear wheel drive cars are regularly using. Doesn't appear to be the same issue as the threads not being run but very odd this would happen under these conditions.

Curious, when you initially installed them what did you torque or tighten them to?

I would put those washers on them

Very interesting. Last month I noticed my passenger side Fox 2.0 shock upper nut was loose. I installed them roughly 6 months ago and assumed I did not tighten them down hard enough. I tightened my top nut down until I had to use a good amount of force to turn the shock body. I will definitely be keeping an eye on them after reading this thread, if they come loose again I will be purchasing the bushings linked above.
Update here: I contacted Don Thuren and after inspection on removal, confirmed the top shock mounting bolt was way over torqued by my local shop. The lower rubber bushing was so deformed that it was flattened and pushed down over the top of the shock. I had to peel it off with pliers I got the replacements from Thuren that are about 1/4” taller. On install, I found they have too much height and there are no threads exposed to thread on the top shock bolt. I ended up using the taller bushing on the bottom and the OE replacement (I bought extras) on the top. Still have 3-4 threads showing with this tightened enough that I can still turn the shock with my hand. Thuren was clear you don’t want to over torque and checking in with them, they seem to think this fix is good.
I will add that the Thuren tuned Fox 2.0 shocks front and back make a dramatic improvement in ride quality especially on washboard roads.

This is why I asked before about the torque applied on install. They are very specific about pintop install for both soft and hard bushing to allow the shock to move or pitch with the suspension travel... Too much torque can actually rip the pin top stud out of the top of the shock housing... Happy to hear that didn't happen with yours. Why shops do this is beyond me...

The top stem on the front shocks has no torque value. Once the nut makes contact with the washer with resistance. Turn it 2-3 full rotation and good. If you start to balloon the bushing then too tight.

This is what I followed when installing mine...
