Sounds like you may need a driveshaft spacer and a shim couldn't hurt either.

drive shaft vibration from dead stop acceleration after lift
Recently lifted my 2015 2wd titan with 4 inch maxtrac spindles,billstein 5100 on the middle setting, 1.5 spacer, moog 4x4 coil springs, and dirt king uca's. For the rear i did a 4" tapered lift block that came with the maxtrac lift kit, also i did a carrier bearing drop bracket, the truck has a slight cali lean. since the lift iv'e been getting a vibration when taking off from a dead stop and it gets worse the harder you accelerate but doesn't vibrate while driving its on on initial take off. I took it to a lift shop and they had if for 2 day and couldn't figure out the problem and i read on here that i might need a shim for the rear end. does anyone know if that could fix it and what degree shim i should use? almost forgot to mention i also have cjd traction bars

Axle wrap? (Disregard, I see you have traction bars now that I finish reading.....)
i thought drive shaft spacers were only for 4wd titans and not needed for the 2wdSounds like you may need a driveshaft spacer and a shim couldn't hurt either.

its defiantly not axle wrap it feels different than thatAxle wrap? (Disregard, I see you have traction bars now that I finish reading.....)
Does anyone have a lift setup similar to mine??
I have the same issue as the OP. I installed a 6" Rough Country suspension lift that came with tapered blocks on my 2007 2WD KC w/35x20x12.50, I also installed RC traction bars. While the traction bars slightly reduced the vibration on takeoff its definitely still noticeable and it gets more aggressive with acceleration, however it then drops off after 10-15mph. If I take off super slow and roll into acceleration it doesn't happen. I am lost as to what I should do next and any insight would be greatly appreciated. FYI I looked under the vehicle (w/o angle finder) and didn't see anything concerning, I get that with a naked eye it would be hard to tell if I needed a 1 degree shim or not. Just seeing if anyone else on here has gone through a similar issue and what there solution ended up being? Thanks in advance.
You can have a driveline shop balance the shaft. I removed my shaft on a yukon years ago to have u joints installed and he also spun it on a lathe and added weights. I can't imagine they charge a lot if you removed it. might be a good starting point.
Yea thats also a great option, I will look around for a shop that can support that effort, thanks for replying!
