OK , so I went out and put the TeraFlex 2.5" BB in and all is great except I still have that factory rake. Can I add a 3/4 spacer as well to level out the front end? I realize I will have to also add adjustable lower control arms at some point to bring the caster back to spec, but just wondering if it's OK to stack the spacers..

 

Let's put it this way...I don't think it's recommended but it will work. If you view it as a temporary solution to something you will improve in the near future, I say go for it. If it's something you plan for long term, I would say spend the money on new front springs.
