lifting with add a leaf and 5100s

I am trying to learn all I can from you all about this subject and I thank you for all the time and effort you all put into helping a brother out...My questions...I want to put 5100s in front with the 1.75(?) setting .In combination I want to put an add aleaf in the rear which will raise it up 1.5. 1st..can I add a leaf in conjunction with 5100s in the rear and 2- if the leaf adjustment in rear is lifting the truck 1.5" in rear should I increase the front height to the 2.25(highest) setting in the front?..and if I do that will I do any damage to my drive system..One more and I know this will make some of you snicker..but Im new to this...will all of this increase the distance my differential etc from the ground? (ok more than 2 questions)...From what I have already learned from you guys I think I know the answers .. but I want to make sure I will be doing this right .thanks guys!

 

I did 1.75 front and 1.5 aal with non tsb spring bilstein front and back. I actually got 1.75" in the back too. It raises the front dif. but the back can only be raised with larger tires. 2.25 on the front can cause some alignment problems and cv joint problems. (search)
