How does the 4A work?

Any resolution on this? Are you still getting chatter and vibration? I ask because I’m now getting it as well in Sport. Interestingly this also occurred only post-lift for me too- BUT - I used perch collars so there was no alteration to suspension geometry as had been discussed in this thread.

I thought perhaps it was the 37s input on because it wasn’t doing this after the lift only after the tires did I notice it. Are you running larger tires?

Very interested to know the current statues of your

You have a WT, the stock SAS tires are 55 lbs. each (super light for a tire that's 34.4" diameter). Depending on what 37s you went with, there is likely a huge difference in rotating mass. My 37" Trail Grapplers weigh 89 lbs. each. You're gonna get some big changes in feel.

Agreed… I went with Falken ATW3s in 37/12.5/17. They only weight 74 lbs each. So not as dramatic as your TGs for sure but I certainly expect some alteration. That said I could honestly careless as long as I’m not fucking up the drive train by failing to address a significant problem or one in the making. Other than this singular issue (and a mild hit to MOG of course) I would do the perch collars on 37s 10/10 times over again.
