Your truck is sweet! I have the same wheels on my 2014 Ram.Check out my build thread in my sig.
I did a Toytec Boss Ultimate lift in the front, and normal Toytec ultimate lift in the back. Ended up being a 2.5" in the front and about 1-1.5" in the back. Turned out nice, and with 285/65-r18 tires.. Had to do a front liner push forward, and cut the limited front fender plastic a bit. Worth the $1800 or so for the Boss 2.5 lift though, at least in my mind...
Here's our 2014 LE
XREAS removed, replaced with Sonoran Steel 3 inch lift, 275/60/20 Yokohama Geolander A/T G015, Spidertrax 1.25 waiting to be installed
I considered a spacer lift, decided to bite the bullet and just switch it all out now.
Thanks for the replay guys and I want to rid the XREAS but that's not in the plan for now.
