Stiff suspension help

i think im going to get a whole new lift kit, springs shocks yata yata. as far as 6 inch lift kit what brand would be the best? i want more articulation out of my front end while being a nice ride. back end im going to get new leaf spring and bilstein 5100s shocks. front im not sure what coil overs i should get. and what does a diff drop do??? thanks for all the help

 

A diff drop lowers the front differential so that the CVs are at a reasonable angle and last longer.

For a 6 inch front lift for articulation (aka no DB lift) I am kinda thinking of long travel as the only way to go there*... And that probably would not get you 6 inches, someone knows more than me on that

for the rear you will need extended shocks, like maybe a 5125 iirc or something along those lines...

*EDIT: or a Solid axle swap...
