Vibration after installing 2.5” lift

Same thing happened to me. You need to drop your transfer case about 1".
I matched the bolt thread at Home Depot but got 1" longer and used two nuts as spacers between the frame and skid.
You could buy a TC drop kit but this is cheaper and quicker. I'm putting a SYE on soon so I didn't care about getting something cleaner

Have you measured the springs to see how much actual lift you got? Advertised lift height is often not what you get. Easy fix is a transfer case drop or motor mount lift. I'd personally lean towards the motor lift as I feel lowering the pan looks bad and defeats half the clearance gains you made with the lift.

After installing a ProComp 2" lift on my '01 Sport I also had driveline vibrations which required me to install a TC drop of 1".
The SYE really is the proper resolution to the vibrations, but the SYE kit and driveshaft will cost $400-800 and that doesn't include $500-800 in labor ( depends upon local labor rates ) IF you cannot do the work yourself...
IF you decide to install the MML; check the cooling fan blade shroud clearance after you installed the motor mounts.

Some springs are not the advertised 2.5"
Condition/age/mileage of your u-joints are?
We've installed several 2.5" springs (legit 2.5") and if the u-joints are good or replaced with new no issues.
Did you get different tires with the lift?
On a side note were you installing just for a look or off road function. If for off roading did you get swar bar disconnects for your new lift height?

I'd advise going to a 15x8 wheel with a 3.75 Back Spacing
It will stick out past the flare a small bit but not ignorantly so.
Also what about the sway bar links.

I wish. This happened on a 4 inch lift with a 1.5 inch tc drop.. almost a year ago too. Stock driveshafts too. Just rebuilt the tranny too and it went kaboom because of u joint failure. It was giving 0 vibes too until it all of a sudden broke. I bought a junkyard one and put a sye and have had 0 problems since lol
Hot damn.
Vibs or no vibs is not a good rule of thumb as I have come to learn when making sure the drive line is dialed in but to each their own.
