A cheap way to get started is a 1-1.25" Body Lift for about $100. Then add springs later.
Another way to go is a 2" Budget Boost spacer lift. Basically 2" pucks that sit ontop of your stock springs. (~$100)
3rd option is to get 2" springs like BDS.
Basically when you go above a 2" lift, then you need to get shocks and links.
