Just bought a 2010 Supercrew 4x4 -
I'm planning on having a leveling kit installed - probably 2.5".
Then adding on some tires to the factory 20" wheels.
Not sure what size tire I'll end up with just yet. I want something a little taller/wider but I don't want to sacrifice turning ability.
My old truck had 35x12.50 terragrapplers(05 Supercrew) and it rubbed the control arms pretty bad. I had helper springs on the rear of the old truck as well... but I never really cared for them. The shackles were noisy going over rough terrain.

So, that being said - should I worry with installing rear blocks or no?

I will be pulling a small boat and a utility trailer from time to time. But mostly just everyday driving... Hunting/fishing... etc...

Lets hear some thoughts on rear blocks....

 

you already have one and unless you want to do AAL or custom leaf packs then theres not problem with them
