FWIW...
I have an '18 SCREW with 10k miles on it and I'll start off saying this is my first raptor and I have been a Chevy guy for ever, my last truck was a '16 LTZ SCREW that I had a Brenthel kit on with Kings, Deavers, shackles etc. Bone stock the raptor was infinitely better. My truck is 50/50 on/off road I work in west Texas and i beat the snot out of my truck daily. I drive the raptor like i hate it and it takes everything i throw at it without skipping a beat. The truck makes me drive like a pissed off teenager. Running up and down lease roads with the traction control turned off enough that I was nearly in need of new tires so naturally I bought some new wheels and decided i wanted to run 37s. I called RPG and got some Deaver +3s, Air Bump Kit and I opted for the Fox 3.0 upgrade front and rear as well. I've had the setup installed on the truck for a little over a week and I have managed to put about 300mi of lease roads on the new goodies and I am quite pleased with the performance I am still tinkering with settings on the Bypass' but all in all its a kick@$$ setup. The rears are noisy for sure but no more than the Kings i had on the last truck. I can't say enough about the rear setup, its a completely different truck under power and if you drive your truck like you stole it like i find myself doing the moment traction control gets turned off, it will change your life going to the setup i have. Sure it was spendy but I have about 5k net less into this truck compared to my last Silverado and it isn't even close on which truck performs better off road. I have run Kings exclusively in the past and this is my first run with Fox and I am not disappointed in the least. That said time will be the true test as I tend to be pretty hard on stuff.
