Long travel kit for 2wd

i have a 2004 dc 4x2 and I'm looking to improve off roading/crawling. I'm not about to sell my truck for a 4x4 since I've only had it a year and put quite a bit of money in it. I want to know the best solution that will help me out with this issue. I understand the best solution would be to buy a 4wd so don't try to tell me I need to sell it, I'm just looking for the best alternative. I've heard a long travel or solid axel kit would help out a lot but I need opinions on that.

 

A few times a month, when I bought the truck I never considered crawling something I'd want to be able to do since before I was more of a "haul ass down every dirt road" kind of guy. I'm not planning on doing any crazy trails because there's not much around my town. I hunt quite a bit and my usual spots get kind of tough, I just want to know what would help me out

 

I'd like to keep it around 2500 but you get what You pay for

 

How much would that run me?

 

Sounds about right, I looked into camburg cuz I've heard a lot of positive feed back on them. OME is the brand?
