my girl friend wants to lift her tj with her tax money. i am a die hard chevy man and i dont know alot about jeeps so i am looking for the best way to lift it cheaply and safely. i have been looking abd i see alot about budget boosts? looks basically like just a 2in. coil spacer. are these a good way to go if not whats some other options. she really only wants to clear 31s or 33s so it doesnt need to be stupid big just a little extra flavor.input is appreciated.
