lowering rear of B2200

I am very new to this but my ? is how far can you lower a rear end with out changing any rear end angles, my truck is a daily driver on 16's. I have 3 inch blocks with all leafs in with an overload spring too.. Please help.

take the springs out and fourlink it with bags.... or you can take all but the top and bottom spring and put in a 4 inch angled block...

If I do the spring and block way what angle blocks do I need to use

hey listen you can go down way further than that without an angle shim i ran a monoleaf (with overload) and a 3 inch block with no shim for 2 years or something never had a problem. but if you want you can throw in like a 3degree or something its not as important as youd think.

I put 600 miles aweek on my truck I want to do it rightthe first time, which springs do I leave in then?.

leave in the longest and the shortest..

thank you for the help.
