will this work

i am looking into getting the RE6030 which is the 3.5 superflex with full leaf packs and was thinking of getting a 2inch spacer in the front would it work or should i just go with the 4.5 with full leaves. Money is the only problem what do you think

If you go with the RE 3.5" sf, without ca drop brackets your suspension geometry would not be optimal with the spacers.

so would i just be better of with the 4.5?
