Billet aluminum Low-Profile thermostat housing for LS engines.
This new housing is designed to turn the coolant inlet to the 6 o'clock position, which helps when retrofitting an LS into older vehicles.
It will enable you to have the lower radiator hose tucked between the rails instead of coming from the side at the stock position.
The housings are short for maximum clearance. They are machined from 6061 Billet Aluminum and are a one piece unit. They are available for LS1, LS2 or an LS3 water pump.
