lift question

ive looked around for this and havent found anything but i was wondering if anyone had done a 3 in suspension lift with a 3 in block lift?? and if this was a bad idea or doable... im looking at the toytec 3 in suspension with the ready lift block set... im not doing any hard off roading but still doing some plus wanted to know what the biggest tires i could fit with such a lift would be

 

Leave the block, and spacer kits alone. The front suspension will bottom out BEFORE hitting the bump stops. This will eventually lead to catastrophic strut failure. (Per Billstien's website). Save your money and get a quality lift!

Keep in mind: Larger tires might require regearing your rearend.

 

didnt think of that would it be better to try to build a kit or buy a presetup kit and what all pieces do i need if i buy in pieces
