One possible solution might be to install thrust bearings. Might help at the extremes where the suspension is twisting the most.Hi, we double checked all nuts and links. not an issue from those. The noise does not appear all time and is not very loud. The seller told me to let the suspension settle a couple of days but I am not sure how it will went away just like that. I have also taken some picture of the front springs and to spirals which are very close to each other and there are clearly marks of ripped paint because are touching themselves.
Another big issue I have noticed: inside dampers box there was a manual for installation and setting up the adjustment knob where it was completely wrong.
On youtube, everyone are going counterclockwise being the softest position and from there you start the counting clockwise to desired position while the manual it was saying to go full clockwise and then count to desired position counterclockwise! I removed the rear dampers and pushed them down and youtube version was correct. This is a very unfortunate error from UPP.
Actually the manual was explaining in the exact way as adjustable Tein EnduraProplus which also are identical in term of psysical dimensions (!) which even UPP acknowledged that is true. Before this setup I had for 2 months the EnduraPro Plus with OEM springs (MY Performance 2023) and I was expected a more increase in confort but unfortunately I was dissapointed. The mild springs from UPP are smoothing out only very small bumps or small imperfections but going over potholes or speedbumps is worse than Tein combination with OEM springs and somewhat similar to original tesla suspension.
I wrote about all issues via support UPP email address but they are replying very slow or not at all!
Then why UPP didn't provide in the package those thrust bearing? They are cheap actually or at least they could mention about them because I am not happy to pay hundreds bucks at service shop to have them dissasembled several times just to make them work properly. However, this won't fix the clattering noise over some bumps that I start to hear after to days of installation. I'm already regretting this because the previous setup (tein enduraPro+ with oem springs) was softer than luxury suspension kit with their mild springs and I am thinking to go back to it or the new Flex z coilovers that are supposed to have the issues fixed, there is a new part specifically for 3/Y performance 2022+ only.One possible solution might be to install thrust bearings. Might help at the extremes where the suspension is twisting the most.
I doubt Tesla would install aftermarket shocks, but I guess it doesn't hurt to check.I'm planning on getting Konis from TireRack. However, I checked with them and they don't have any installers who work on Teslas in the San Francisco Bay Area.
- They recommended talking to Tesla. Has anyone used Tesla to install third party shocks?
- Anyone know anyone in the Bay Area? LA? (I need a good reason to go to LA.)
I hope OP hasn't reused them!one time use nuts
I hope OP hasn't reused them!
One time nuts are made to crush the threads at the specified torque. After that one time they should be considered done for duty not reused with loctite.
Thanks! First I've heard of threads crushing nuts. I've heard of one time use torque to yield bolts.Yes, the UCM nut and the stabilizer bar nut for the front have to be replaced

Nyloc nuts for the top of the strut, Koni's come with them...
This is correct! The internal valve of Koni reacts faster when tires are at recommended pressure.One other note about Koni Special Active shocks and tire PSI:
I had the PSI lowered to 38-ish since the recommended 42 was unbearable with the factory shocks - constant drumming in the back.
With these shocks, I noticed that it's the opposite. When inflated back up to 42 PSI seems to ride better and solve some of the cons I mentioned in the previous post. Interesting...
Yes, Tesla are selling them as full assembly on front and rear dampers are sold with upper mount including the dust cover/bump stops in one part. The only way is to find them from scrapyard with totaled cars.Would anyone know if there is a way to buy OEM bump stops separately?
(So far from my findings, Tesla only sells the whole shock assembly as one?)
Are there any alternate bump stops for us? 3rd-party perhaps?Yes, Tesla are selling them as full assembly on front and rear dampers are sold with upper mount including the dust cover/bump stops in one part. The only way is to find them from scrapyard with totaled cars.

Any more longer term comments on your Koni Special Active shocks?..'Bumpstops are carefully tuned for use with Dinan springs.'
Loving them so far. Everyone who rides in it now says it's much smoother. Still surprised by the added handling improvements, which I did not want and asked for anyway.Any more longer term comments on your Koni Special Active shocks?
Still would likely work better than trimming the original ones for non-Dinan springs...'Bumpstops are carefully tuned for use with Dinan springs.'
