2014 Silvy Crew,_ Motofab 2 1/2 up front and Ebay 1" block in rear, Falken wildpeaks 285/65/18 , when i first started looking at the lifts seemed 2' had more rake than i liked so I compensated, bought a 2 1/2" up front, alot of pics on the NEW trucks seem pretty level however, on mine once installed then the back sat 1/2' lower..WHY because a 3 yr old truck with a seasoned suspension. So answered issue with 1' rear lift, to do it over i would of went with 2 or 2.25 front lift
