Thermostat Housing

Billet aluminum Low-Profile thermostat housing for LS engines.

This new housing is designed with the coolant inlet at the 6 o'clock position, which helps when retrofitting an LS into older vehicles.

It will allow you to route the lower radiator hose between the frame rails instead of coming in from the side like the OEM unit.

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 and LS2 or LS3 water pumps.

  • Concept ONE LS Kits (6-rib), HD LS kits (8-rib), and Supercharged LS kits (8-rib)
  • Edelbrock water pump - PN 8896
