Help!
 

I want to get a suspension lift on my truck, i am fairly car/truck savvy but not an expert or anything. Ive been reading about all these people who lift their trucks then have to adjust the driveline or gearing ratios, etc. Is this necessary or is it just to juice out all the power they can. I am maily getting it for aesthetics but may play around in a muddy field. (i only have 2wd) If i have to adjust mechanical stuff can i take it to a shop to get it done or is it a home job?? Thanks, anything helps.
