My brother in law works at a local NAPA, so one day we looked through the catalogs for some extended brake lines for my Scrambler. I have 2" body lift, 5" suspension lift, swapped in Scout II Dana 44's F/R (full length), am running 33" Swampers and will go to 38" Boggers after the 350 installation next year (hopefully). I didn't want to go with the "fits 4" lift" lines because that's all they fit and I've seen them pull apart (braided stainless ones especially). We found some, I don't know what they fit, but they're 36" long and regular (OEM) rubber ones. The holes weren't the right size, so we drilled them out on a press and deburred them. They work great and I have never had any problems. I did have a problem with a caliper, and it's nice to be able to unbolt the caliper and place it on the fender, with the line still attached. The rear one I bought for an early 80's F-series truck, it was 6" longer than stock and also works great. The only problem I had with the front lines was routing them so the tires didn't catch or have them get snagged on brush.
I hope this helps and happy wheeling!
