suspension upgrades/questions

[bigyellow]

i wanna do a 3/5 drop on my truck. i was looking around and i can get the 3" springs for the front from CPP for 95 dollars. and i can get just the rear 5" drop springs for the back from gmcpauls for 120 if i remember correctly.

my question is do i have to use the drop spindles and a one inch drop spring on the front or would i be able to get away with just the 3" springs. and the back do i have to get the trac bar?

yes i'm aware that there is dozens of posts on here that will probably answer my questions but all of the info in spread across too many threads and conflict each other. so if anybody is running this set up i'd really appreciate it.
