Got this to replace the factory rubber rear brake hose on my TJ after my 4.5" RE height. The factory hose was tight and when I corrected the gait angle he definitely didn't like it. Replaced it with this stainless line from RE and now there's plenty of room for flex. While I know you shouldn't notice, I swear my brakes feel "harder" afterwards, which is a nice bonus. Maybe my factory lines were old enough to give them a lot more or something.
