Well if I will have to change out my rear axle too, I don't think I will mess with it. My trackick is a daily driver, and while I have someone who is going to be helping me with this project (dad is an auto mechanic), it would still be a lot of work from what I've seen.
Are the benefits really that great? It is mainly a strength issue it seems to me, but I don't really know. I'm not going to be doing any rock crawling, as there are absolutely 0 rocks in Florida, so its going to be entirely mud sand and maybe some small hills.
