Finally got my VIN today after a 6 week wait. Truck should be here early to mid April so I'm basically ready to start ordering mods. Just wanted to shoot a couple questions by you guys to get some final opinions.

I'm planning on getting 305/55/20s (33.5x12.5 in) on 20x9 +18 wheels.

I know I need to raise the front some, but I'm split between the BDS 2.5'' level, and the F150Lifts 3'' Boss coilovers. Both have been discussed here on the forums and they both seem like good choices. I do some light off-roading and beach driving but nothing too intense. What benefit might I get from the coilovers to be worth the additional cost increase?

My other question is whether or not to upsize the rear block. I don't tow much at all, carry large weight infrequently in the bed, and like the mostly level look. Is there any reason for me to change out the rear block?

Any advice is much appreciated.
