[Col Clank]

This is what I am thinking about ordering for my 1981 C10 but haven't decided it is gonna run me $1452 trying to see if I can get the air management kit cheaper somewhere else.... Also is this enough air to support just raising and lowering to drive no hopping? Any help would be wonderful, thanks.
