was going to get this to lift 3" u guys recommend it

I was going to order this to lift my truck 3"
for the front
and also the spacer above to get me the full 3" but im worried because it says its not recommended for use with spacers is anyone else running this?

and the rear

but im confused on the rear is this the only thing i need to lift the rear is the shock or do i need to add something to that as well?

and is this the cheapest place to order this from if this is a good setup?
Thanks

 

chris do i have anyother options to get a full 3" from the billy 5100s then?

 

also i will not be doing any offroading but i live out in the where there are some rough roads and lots of potholes

 

do the billys already come preloaded or how do u change to diffrent settings i obviously want the front at 2.5" so i can get my full 3" and how about the rear i am getting the tsb done tuesday so I will be ordering this
so what would i want to set the rear at so it is as close to level with the front?
Thanks

 

and this may be stupid question but is this considered a body lift because i was reading another post and they said this is a body lift and they wouldn't recomend it. Would u recommend something else chris for a really good bang for my buck or is this a good way to lift it. Will it look roughly the same as any other 3" lift kit?

 

just a last check b4 i order
i need front and rear billyy 5100s, 2 front top plate spacers 1/4", UCA's will i be fine with light racing?
and do i need a front diff drop? what exactly does that do?

Thanks so much u have been a huge help

 

r u using a diff drop do u think i need it?

 

but i don't really understand i guess its not gonna take 1" away from the lift is it?

 

if you get the billys get them from downsouth you can save 150 doing that
