The Granatelli billet thermostat housing is a direct-replacement housing for GM LT series engines from model years cited as 2014–2019, covering LT1, LT2, LT4 and LT5 passenger cars and trucks. It accepts LS-style thermostats as noted, offering a billet alternative to OE housings for installations that require that specific thermostat interface and GM LT compatibility.
