Rear spring modding?

[Stroke4Fun]

I have a 3.5" icon lift with the spacer in front and 5.5" Pmf traction blocks in the rear i have all the icon parts to raise the front to 4.5". The rear sit 1" higher right now when i do the 4.5" it will be level without the spacer's i want to leave the spacers in so the rear would need to come up atleast 1" maybe 2". I dont want to do add a leafs due to the harsh ride the other option was
mini spring packs i was thinking of getting a spare set of stock springs ditching the fat lower leaf and stack maybe 3 thin leafs in the pack i know the thin leafs will ride better just don't know about the amount of lift or load it will provide anyone try something like this before and can shed some light on the subject?

I would either get some taller blocks from PMF or go with some mini packs from Carli. They will give you around 2.5" of lift and will make the ride a littler better in the process. I've got a set that I will be putting on my truck in the coming week or so.
