This block is not tapered. In our opinion, it takes about a 2.5" level to get the 2009-2017 F150s to a "dead-level" stance. The Boss Coilovers at 2.75" of front leveling result in a slight amount of rear rake, and using a 3" block in conjunction with the Boss Coilovers will get you back a good amount of front rake, though it will be slightly less than stock.
