Allstar Billet Aluminum Swivel Water Necks

These billet aluminum water necks fit most Chevy V8, accept most standard thermostats and swivel a full 360 degree to simplify connection of LH or RH radiator hoses to engine. Black anodized finish helps protect against corrosion. Stainless steel hardware and an o-ring for sealing the base of the water neck to engine are included.
