If you are looking to remove your heater system, this provides a simple solution that rids the unwanted mess under the hood, is drop-in ready, and gives your race/pull truck a tidy engine bay. Our billet aluminum fittings eliminate the need for the factory coolant feed and coolant return hoses coming from the heater core on the LB7, LLY, and LBZ platforms. The HHPE GM HEATER CORE RACE FITTINGS (01-07.5 GM) utilize the factory thermostat housing bolt and the factory lower coolant hose and clamp.
