The DFC front-left upper brake hose for 2017-2018 Ram 2500 models is a replacement brake line that restores the hydraulic connection between the chassis hard line and the front caliper. It fits the specified front-left upper position on those Ram 2500 applications and is intended as a vehicle-specific replacement to return reliable hydraulic braking at that wheel.
