KING coilover question

quick question. I pulled the trigger on some king coilovers. I want to get a full 3 inches of lift on my truck (access cab with no armor) I also got a set of 1/4 top hat spacers and a Set of 1/2 spacers. How would I achieve the best ride? Using only the coilovers preloaded to 3in or preloading a little bit less with the 1/2 spacers bolted on top. Or would it be better to preload a little less than that and use the 1/4 spacers on top. I don’t want to preload so much it ruins the ride that’s why I’m wondering ONE of the sets of spacers would help.

 

Anybody??
