I'm not say your wrong but I still don't see why it's better. In fact, by using after market shocks you are limiting down travel. A 4" suspension lift would maintain factory angles and travel. Assuming the shocks allow. I would think an icon or fox at the top setting would work well with a 4" kit.
so wait. what 4" kit are we talking about? what intended use for YOUR truck are you hoping for? what are you trying to accomplish.
i explained to you how to go up in height, safely, while maintaining a ride quality the same or better than stock and improving high speed offroad performance.
now that doesn't sound like what you're looking for. so what is it?
