4/6 Drop ??

[isotek]

I want to know what I will need to lower my truck to 4/6. I already have some parts I bought to lower it but changed my mind in the process of doing it. I have 2'' front springs and 5'' lowered shocks. I want the truck level no rake, so if I bought 2.5 drop spindles and 6'' rear spings that would give me 4.5'' front and 6'' back, would that be level or close to level and would I need the shock mount relocators???? This is my first build so i'm learning but I learn fast. Thanks in advance
