What drop do you have on your truck and what did you do to get it there? I am doing a drop on my 4WD Silvy and I am wondering if I am going to have any vibration issues.

I did a 3/4 or 4/5 drop. Can't remember exactly. The DJM kit, Front LCA's, Rear hangers and shackles. My guess is yes you will have vibration.

I am hoping I will not have any issues! I am doing the Belltech front spindles for a 2" drop in the front. For the rear, I am removing the 2" 4WD lift block and installing Belltech 2" drop shackles for a total of a 4" drop. Still think I will have a problem?

I'm no expert at it. I did and a lot do when they drop the rears. Chances are good you will IMO.
