Arnott AS-3380 suspension

[jcpetit]

Hello,
does anyone replace their suspension with Arnott ones (AS-3380) ?
Is the ride better and quieter?

Following...

My left side front air strut is rattling like a mofo (and no, is not the stabilizer bar links, I already replaced those). Its just an annoying rattle over bumps.

Local service center said they thought it was design flaw in the strut, but I am out of warranty so they want like 900 for it.

I feel you. The same thing happened to me.
But the expensive new struts (1067361-77-C) seem to have the same issue after a few months:

Rattle noise coming from front Air Suspension (2017-18)

You have two sounds in this video, the first one come from the air suspension struts and the second, the clicking sound, service fixed that one for me by placing some material similar to dynamats between the shock tower brace and the shock tower. This need to be done on both sides to work. If...

So I'm looking for an alternative...

I changed my front struts for the Arnott AS-3380. It's been now 3 months and so far, they are excellent!
The riding is excellent and the weird noise from the suspension is gone Very happy.
Even my Tesla SC noticed that the ride is better
I'm planning to get the rear ones (AS-3381) to replace my old struts as one is starting to lose air...

I just changed the rear ones. Well, I'm very pleased The ride is (much) better
Smoother ride, less road noise, seems more responsive on turns. Best of all, no more weird suspension noises...
My Tesla feels just more "solid" on the road.
Very happy
Note: my Model S is 2016 with AP1 and almost 150,000 km. So the struts were probably a bit worn out. But my EV garage is used to drive a lot of Teslas are they were amazingly surprised with the results. Let's see how they handle in the long run

Hi!
Curious about the Arnott struts you have changed - still good?
Rattling noise still gone?

Unfortunately, on the noise level, they are not as good as the OEM or Unplugged ones..

 

[Martin Mayer]

So - after some time of usage - those aftermarket struts have the same issue with the rattling noise like the OEM ones?
Then it seems that they have copied the mistake from the OEM product...?

 

[jcpetit]

They are quite different (not a copy) but yes, they are not as silent as the OEM 77-C.

I'm suspicious of this noise. I don't really see what within the air bag could cause such a rattle. I'm curious to see if the UP shocks fix the problem....and if so, then maybe the noise is isolated within the OEM shock.

Thanks for sharing your experience with the aftermarket product. I think I´m going to continue with my rattling OEM ones for the moment...
However - quite disappointing that Tesla doesn´t provide a sustainable fix for this common problem that has been around already for many years now...
