Problem since adding lift / leveling kit

I recently installed a 2 1/2 in lift/leveling kit and 19" wheels. Now when I first apply the gas I get a slight vibration for about 3 seconds. Do I need to install different shocks or is it something else???

 

I believe the rule of thumb is 2", and above, you'll need a carrier bearing drop kit. It's basically a $12 spacer. I drove around for about a week before installing mine (I have a 2" lift), and I had a noticeable shudder when first taking off from a dead stop. I then installed the carrier bearing spacer, and it's now ~95% gone. I can still detect it, but only because I'm looking for it. If this thing was in there from the start, I don't think I would have ever noticed it.

 

Thanks! It's been driving me crazy. I give it a shot

 

No problem man.

Good luck.
