if you are on a budget. STOP now.
most likely you are at around 5 at least. 2 more inches will net you at 7. at seven inches and short arms not only will your articulation suffer, and any hint of decent ride quality dissapear, but you will be very high for 33s. if you want more flex just trim the fenders.
there is a lot more to worry about than you think.
do you have an SYE youll need one.
do you have a DS that will work with the SYE, youll need one.
do you have extended brake lines, long ones. youll need them.
how about gears. i assume you want to go bigger tires soon too. please dont tell me you havent thought about gears?
if its just because you want it to look bigger and you dont care about going on the highway, or offroading. you can get 2 inch poly spacers and 2" lift shackles. unless you already have shackles, then sell your leaf pack and buy a 6.5 inch leaft pack and get a .75" lift shackle.
its not as easy as you think to just, "go bigger". there are alot of things to consider. especially cost...
