So I have had the truck for two months, put on B&B exhaust, tires and wheels, and finally got around to the lowering kit(x-metal). I like it alot. My only issue is when pulling my car to the track I am feeling something bouncing in the rearend of the truck. It is happening at acceleration from a dead stop only. Will air bags help this and/or eliminate this? If so any recommendations on brand or style would be great.
