    Manufacturer's Part Number:

    Billet Specialties Thermostat Housings are engineered to help route coolant hoses in engines with limited space. Because many custom vehicles and street rods have limited engine compartment space, odd directional placement of the radiator neck is common.  The versatility of these Billet Specialties Thermostat Housings allows positioning of a radiator hose in almost any direction. Available in straight-up or angled neck, swivel or fixed base and barbed or AN fitting to ensure the perfect hose geometry for any cooling system can be routed. Billet Specialties Thermostat Housings accept all major name brand thermostats, include an O-ring and are offered in machined, polished or black anodized finishes.


    • Available In straight-up or 0, 15 and 45 degree angled neck
    • Fixed or swivel design
    • Classic barbed or AN attachment styles
    • Offered in machined, polished & black anodized finishes
    • All thermostat housings include an O-ring and mounting hardware

    90420 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Billet Swivel Neck T-Stat Housing Even though this housing is taller I was able to use my same hose and the leak was fixed from replacing my old cast housing. Expensive but worth it, looks good and seals good.
