Honestly 33's and a five inch lift is a bit much for such a low hp engine. I'm not sure what your plans are for your truck, but I'd keep the lift to 2-3 inches and run some 31's. The engine is still gonna struggle on hills and your gas milage will suffer, but it won't be as bad. As far as adding a body lift to 5 inches of suspension lift, again I wouldn't recommend it. A seven inch lift with 33's and an engine that puts out under a 100 hp. Unless you plan on re-gearing your really going to be crawling along. Especially on a nice windy day. My 2 cents.
