Ride quality is actually determined by a combination of shocks, air bags, HCV. Setting the rod height to only have 11 inches of clearance might feel softer but its actually more damaging to components. Same as setting it to high. I only say this as i was an auto transport driver and we had 2 trucks custom built for Alaska use. A lot of engineering goes into setting ride height. Ride height also plays a major role in determining drive line angles. Getting U joints into a bind in some cases. Other times wearing a pinion gear or seal far faster than they should. If you're really looking for a more rapid reaction from the suspension and airbags there are ways. First i would determine the type of HCV you have, standard action or rapid? Because these systems use 4 bags per axle and 2 on the tag you can install quick relief valves in line as well. What these do is... when a tire hits a bump it flexes the airbag bellows and sends the pressurized air (typically) into the next airbag. The quick relief allows this air to be discharged from the system instead. Resulting in a smoother ride feel. Newell uses "ping" tanks to accomplish basically the same thing. Rapid response HCV is also necessary for either of these designs to work properly. The link is the HCV that almost all Alaskan commercial trucks have installed. https://daytonairsuspension.com/products...e-50860014

By replacing the 2 HCV's on the drive axle and the 1 on the steer axle in combination with the Newell ping tank system would be the way i would go. They do require 3/8ths air line as well, they move a ton of air quickly.

From the previous owner they mention upgraded shocks already. Road kings are nice.
