Billet Specialties 90730 - Billet Specialties Swivel Neck Thermostat Housings

Because many customs and street rods have limited engine compartment space, odd placement of the radiator neck is common. Thanks to the swivel design of these housings, you can aim radiator hose in any direction. They accept all major brand thermostats and include an O-ring. Choose from polished or black with a 0°, 15°, or 45° swivel neck.
