If you are installing a big lift: a long travel setup: or a set of portals these can be a HUGE time saver. Each line is 12" long and bolts into your existing brake line. These can be installed at the caliper or master cylinder side. They are all straight banjo fittings on both ends. We use these all the time and absolutely love them. THESE ARE NOT INTENDED FOR ON ROAD USE. SOLD INDIVIDUALLY.
