Pre bent line but needs hand tweaking do to shipping. They had to striaghten sections of the line to fit it in a box. So try not to tweak the old line too much taking it out. Mine was rusted badly and came out in three sections. Make sure to keep the old mounting hardware or buy some new ones since its not included. For 37 bucks it sure beats trying to fab one your self if your in a hurry, took about two hours to replace using a lift and air tools, could be done faster if its not a rust bucket like the beater I replaced the line on. I plan to pick up a full stainless kit for my other mustng based on how well the lines follwed the stock one's. Just wished they sold stock replacement prop valves so I could order the cobra kit instead of having to make a 3-2 port conversion.
