my truck is at stock height right now. and I am want to put 3 inch spacers in the front and 3inch blocks in the back will this work? also hard hard are the spacers to put in the front I have done blocks in the rear end before.

 

spacers are very easy in the front as long as you have a set of spring compressors, however i wouldnt go more than 2 or 2.5 inches if you are not going to relocate the control arms or track bar,
