Stainless lines are cool, but they aren't stronger or more durable than stock rubber lines. Rubber lines stretch when they get caught on something on the trail, but stainless lines usually rip off. Kind of funny that stainless lines are popular as an upgrade, but I've seen them break on the trail 10 to 1 over rubber lines. The benefits of steel lines are custom lengths and slightly better brake feel because the steel line doesn't expand a little like a rubber line can........but most of us would never notice the difference.
YJ or S-10 stock brake lines are longer and bolt right up.
