I have a 4x2 and added a 2.5" leveling kit on front and am doing a 6" fabtech lift soon. I know that this now has the front up 8.5" and the back only 4". The rake is around 2, but this still leaves my back low by almost 3", would it be better to add a 2" OEM block to the rear or to go with a 3" block to give it just a little rear rake so i can tow a flats boat and still have a level ride, i hate the rear sag.

 

It's completly up to you. If you want the rear slightly higher, go for it.

 

also wandell, since you are here, what do you think of an add-a-leaf? Do you think thats a better way to go than stacking 2 blocks on top of one another?
I am looking for a 3" block but they are hard to find too, especially the 2 pin that i need for my truck...oh well ill keep looking. Thank you
