Hey man, you have a great rig to start off with. If you're looking at the budget and a 5.5" long arm isn't in it, then you should look af the LCG (low center of gravity) concept. Yeah, it's the new thing...and I love it. Running 2.5" OME coils with 1" body and 37s, could probly fit 40s with a lil work. All my highline stuff is from Rokmen Offroad; upper and lower control arms, hi fenders, rockers, and corners, they make great stuff. Definitely have to do some cutting, and hope to God you swap axles, but it's doable. I still have stock front D30 (4.88s), but bumped it up to a Rock Jock 60 rear (overkill, but I love it). I just use it knowing that I have a D30 and don't hammer on it. Just my 2 cents but it works, and works well. Pics on my user page.
Hope this helps...enjoy the adventure
