As 10Frank said, you will get many answers but first you need to know what you want from your jeep then go from there. Dont rush into any mods until you know what you want otherwise you will be wasting money and taking it all out.
Amen to those 2 sentences. That's probably some of the best advice you will receive on this forum. I'm going to start a 'rebuild' thread once Brown Santa brings all of the stuff I've ordered that replaces some of the junk I bought when I first started out. It's hard admitting that, but I don't want stuff on my Jeep that can break when you need it most. One thing I'd like to add is to buy the best quality that you can afford, otherwise wait til you can afford it. You'll be pissed at yourself in the long run if you don't.
