1 inch block with Carli Add A Pack
 

I am currently considering adding a 1 inch block to my 2014 SRW 3500 4x4 Crew Cab short bed. The truck currently has a Bilstein 2.3 inch leveling kit with a Carli torsion Sway Bar and Carli adjustable track bar. I then replaced my rear overload springs with the Carli Add a pack in order to bring the back up a little bit and get a little better ride quality out of the truck. This only raised the back of the track by 3/4 to 1 inch. I am beginning to tow and put more weight in the back and am thinking of doing the 1 inch block in the back. I'm not really looking at putting air bags in because I don't want to constantly adjust them or effect my current ride quality. I believe this additional inch will also help my hitch. I have a Gen Y 9 inch drop hitch and worry about it being too low if I put a heavy trailer on the lowest setting. Will this raise the back of the truck too much? What is everyone's take on this set up?

Thanks in advance,
