spacer to 6112 Q

hi all, bought the truck with a 1" spacer up front, since then added general spring 90-297HD's in the rear

6112's are in the garage, 5160's in transit

i'd like to maintain the current stance which has a little bit of rake, so i'd just like to confirm what sort of lift the 1" spacer gives. Checked wheeler's and they advertise a 1 1/8" poly strut top plate spacer giving about 1.25-1.5" of lift

2nd Gen 6112 4x4:
#1 0.60"
#2 1.08"
#3 1.59"
#4 2.15"
#5 2.46"

so would my best bet be to go #3?
