After reading through 135 pages and entirely too many "where are the 6112's?"....I pulled the trigger on 5100's and installed on the 3rd setting and I'm very happy with the results. I was hesitant of the highest setting, as I wanted a little bit of rake, and a slightly better ride (even if it's probably just psychological).
I ended up yielding 1.75" on the 3rd setting. Perfect amount in my opinion. Truck looks damn near level to the eye.
Honestly in terms of ride quality, I can hardly tell any difference from stock on small sharp bumps cracks. However just as everyone has claimed, the truck feels way more planted on larger hits/uneven roads. Way less body roll and dive under braking. And best of all, no more wallowing boat-like feel.
Wheels and Tires being installed as we speak. Big thanks to this thread.
