MIA's Description

The Fleece Performance Heater Feed and Return Hose Kit is an upgrade designed to eliminate the troublesome and leaky quick-connect heater core line found in 2003-2012 RAM trucks. This kit replaces the problematic stock hose and quick-connect fitting with a reliable solution featuring high-temperature silicone hose and a stainless steel barbed riser. It includes Permatex thread sealant and four new hose clamps.
