Pre-bent brake lines are available in OEM or stainless material.
OEM material is recommended if you plan to modify the hard lines, as the stainless version is difficult to bend and flare.
OEM rubber, or DOT stainless flex hoses are available for stock Mopar calipers and DoctorDiff 2 or 4 piston calipers.
You can choose brake combinations that were not offered by the factory, so please make sure you know what you have before you order. What you have and what the car was built with are often two different things.
