Not sure which route to go. I have a 6" Fabtech with 3" BL and 37's.

Will the 3" look too small? Conversely will 4" look too big?

From what I've see on lifted (ie BL) trucks the 3" comes up to the bottom of the grille. How high will the 4" come up?

Lastly does the 4" stick out (away from the truck) considerably more?

Thanks all for your opinions!

 

Go with the 3", the 4" would look too big and out of place unless on a half ton.
