Does anyone make a 4" block for our trucks? I know there is a 5" and a 3" but im not sure of a 4"? If you know of one could you maybe direct me to a link or a reference of somewhere to get one? How much do you think it should run?

 

Rancho makes a 4" block. I actually have a set sitting in my garage with U-bolts b/c I upgraded to 5" Fabtech blocks. PM if you are interested.
