I have a 08 FX4 and had a Pro Comp leveling kit installed. I think it is too level now if that makes sense. Sometimes it even looks like it may be slighlty higher in the front. If I hook up the boat, or carry something in the bed, it is for sure a little higher in the front.
What are my options for raising the rear and inch or so with no, to little, other modifications required to suspension and drive shaft?

 

Replace your OEM 2 inch lift block with a 3 or 4 inch lift block.

 

i agree, don't forget you'll need longer u-bolts to compensate for the larger block.

 

i would go with add a leaf. if youf going to be towing

 

I have a 4x2 and mine sits perfectly level. Can I add a 1" block to the rear? I think I may need the height as well as I will be periodically pulling a camper.

 

i say the best for you is to add airbags..... this way you will ALWAYS be level..... not just when your bed is empty or not towing. its not much more money for the airbags, and gives you the ability to have different weights without looking "goofy". plus, IMO they are an easier install.

 

Thanks gang, I will look into that 3 inch block option.
