I have a 2019 with fox 3.0 live valves. From Fox, there were no turns on the preload and that is stock height. They are adjustable 0-2" from stock. I set mine at 1.5" above stock initially (0.75" on the preload adjusters). I reduced that to .75" above stock (3/8" on preload) after realizing that too much preload puts the shocks at too much compression travel and not enough droop travel. Plus after calling fox, they said the internal bypass settings work best at no more than 1" of added height. I found the truck pretty harsh on top out given there was not enough droop travel (truck could really feel the shocks quickly top out whenever dropping off of something). This is why I lowered the ride height to 3/4" above stock. Your experience may vary, but heads up - this is not an easy adjustment as the shocks have to be removed from the truck to do the adjustment given the lack of space in the coil buckets given where the hoses to the reservoir sit.
