wouldnt a 6" lift (without the preload spacer and the Bils set to stock ride height) be about the same height you have now but the 6" also would give you the flexibility to go up to 2.8" higher in the future if you wanted for a total possible of more than 8" lift?
with the 4" lift and Bils youll always be limited to a hair over 6" with maxed Bils?
just saying.....and yes.....i was someone who came on here looking for 4" lift kits bc i didnt want to go too high with the truck but here i stand today (like so many others) wanting to max out my Bils on the 6" kit i got and get bigger tires lol
I'm not really sure to be honest. I did this build in baby steps to ensure it would fit into my garage.
I got advice from the forums and most agreed that the 6' lift wouldn't be able to get into a garage with a standard 7' door.
I first did the lift only so I still had some factory rake because of the 4" front/3"rear specs of the 4" Superlift kit.
Once I saw that I could get into my garage with room to spare even having the Navigation puck on my roof, I knew I could go higher on the front to level the truck off.
