That's 2" of lift, but the back has the seat out and is likely a higher rate spring .
Some rake is good, as I recently learned, because it compensates for a load, such as camping equipment.
Yours has a lot and I'd decide my ultimate tire height before I did anything, then proceed - based on having more information.
The reason I say that is 2" more on the front is going to get into some other changes to make it work, and dropping the back may be more cost effective.
