Hello. I have a 06 SC Lariat 4x2 that im wanting to raise up a little. Im looking at a spacer up front with 4x4 blocks in the back, but i was wondering. i know the 4x4's sit higher than the 2x4s, so can i use a 4x4's coilovers to get the height? what about spacers on top of that? if i did that, how much would i need to lift the rear?
