Leveling out my truck. Need Help!

I know there are plenty of threads about this but every situation is different. So I bought my truck used and the previous owner put in front spacers to level out the truck without doing an alignment so my tires are worn out. I am getting new tires very soon and I want to keep the "leveled" look but i want to get rid of the spacers. I am thinking about getting the 5100s but I have a couple of questions.

1. If I just get the 5100s for the front, do i need to replace anything else like to coils or any other component?

2. Is 1.75" the right setting for the level look or is it 0.85"

3. If I get them front and rear, can i just get the shocks and that's all and still have the leveled look?

My suspension is all stock except for the spacers. PLEASE HELP!

 

1. No

2. It depends. Measure the front and back then make your choice.

3. Yes

 

thanks for the help man!
