DMS Billet Thermostat Housing with LS3 Style 160 Degree Thermostat for All Gen V LT Engines Dedicated Motorsports brings you a bolt on replacement for the OEM plastic thermostat housing found on all Gen V LT motors. This plastic housing is prone to breakage during engine service or during the loss of a serpentine belt. To prevent this we clocked the top nipple in the same plane as the thermostat inlet. The DMS housing is CNC machined from 6061 billet aluminum and comes with a double o-ring seal to prevent leakage. Fits all L83, L86, LT1, LT4, LT5 Due to the nature of thermostats we will not warranty the actual element. However the housing has a lifetime warranty. May not fit some trucks with aftermarket intakes or superchargers. If you question your fitment make sure to take note of the small 3/8 line placement on the DMS t-stat housing vs the stock unit on your vehicle. LT4 Thermostat Install Guide
