2 in. Tall, Billet Aluminum, SB and BB Chevy Thermostat Housing Riser with Dual 3/8 in. NPT Ports; Includes 1/4 in. and 3/8 in. Barbed Fittings and O-ring.
Trans-Dapt Performance Products billet aluminum thermostat (water neck) risers can serve multiple functions. They are an easy way to create easy (easier) access to manifold or thermostat housing ports. They also facilitate the installation of a water temp sending unit, temperature gauge, or for adding lines to your intake manifold. Lastly, they are ideal for situations when the vehicle's radiator is positioned higher than the intake manifold.
Trans-Dapt CNC machines these risers from durable T6061 aluminum and clear anodizes them for longlasting looks. A captured o-ring is used to ensure a leakproof installation, and a recessed thermostat groove to allow the thermostat to sit flush with the sealing flange.
Each unit has two 3/8 in. NPT ports, and includes a pair of both 1/4 in. and 3/8 in. hosed barb fittings. 1 in. and 2in. models are available.
