Well gents, it FINALLY got done! 6" BDS lift, with full replacement leaf pack (still on stock rear block), 18x10 -19 offset Ion wheels matte black with 305/60/18 Micky Thompson Baja ATZ P3. These are some of my first pics, truck wasn't cleaned by the shop which was a bit of a bummer, but didn't matter much as I got 'er muddy already at work!
Some notes bout track width, often talked about in this thread (by no means do I claim perfect measurement technique, but I did use levels and such and tried to get it right):
-I measured both compared to fender walls and actual track width, front and rear, before the lift (I can't quite say "stock" because this truck came to me with High country wheels, 20x9 +27, and my understanding is that 18x9 +31 was actually stock) and after.
-Compared to the fenders there was already a 1" difference from front to rear, front being wider/rear tucked under more
-Actual track width was 1.25" wider in front before lift. Fenders were at 37" front height, 38" rear height.
-After lift, I measured the front sticking out 1.875" further than the rear (from fenders)
-Actual track width after lift about 3.5" wider in front than rear. Fenders now at 43.75 and 43.25 front and rear (slight squat)
SO, based on my experience I would say the usual line that the BDS kit PUSHES track width out 1.5" per side isn't quite right (my track width went from 1.25" wider to 3.5" wider in front than rear, so just over 1" per side), however, it does push and combined with the initial difference in track width puts you in the 1.5" to 2" range (per side) depending how you measure it. I did take some pics/video of the 'stock' track width difference too, in case you think I'm full of sh.. I'm not saying you're wrong about that, just that I have some proof in this case. And I somehow didn't get the best angle on it but I took the one pic with my level sitting 2" outside the rear sidewall to try to illustrate. I'm going to get spacers to even that out, just trying to decide between 1.5", 1.75", or 2", since I'm sitting at 1.875" difference compared to fenders, but only 1.75" of track width different. I doubt any one would ever notice the difference from the front either direction, but I overthink everything (if you hadn't realized yet by reading this book of a post).
Finally, the Titan in the one pic is my old truck. Funny thing is being the 'off-road edition', it sat about 3" above the stock height of the Chevy, so I'm not that much taller than it now. The look of the new one is MUCH more aggressive though (read: AWESOME)! I do apologize for the long post, just giddy as a school girl right now and wanted to share as much info as I reasonably could.
