Looking to keep your LT powered vehicles engine coolant temps down, we have you covered with the Prospeed 160 degree Billet Thermostat Kit. A redesign of the original we developed back in 2015, these allow use of the tried, true, and abundantly available LS3 thermostats, we have also added a modular air bleed port allowing the 5/16 vent hose to remain in the OEM location or allow it to follow the main coolant hose. This is popular for people running superchargers where the belt might snap and take out the coolant hose barb. The extra 1/8 NPT port can also be utilized as an additional water source or for a coolant pressure sensor. These are machined in house out of USA made 6061 aluminum and come with all hardware as well as a 160 degree thermostat and give a nice billet touch in the engine bay compared to the OEM plastic unit or ugly cast versions.
* The Prospeed machined billet thermostat housings carry a lifetime warranty against failures and defects, however due to the nature of thermostats we do not warranty the thermostat itself
