Our Polished Billet Aluminum Water Filler Necks are CNC machined with a -16AN female straight o-ring port in the front. This allows you to choose the size fitting for your application. Fittings are sold separately for this reason. -20, -16, -12, -10 and -08 AN are fittings available along with radiator hose type fittings.
Billet Water Filler Necks are specifically designed for Dragsters and Race Cars both, providing a higher fill point than the radiator and providing clearance for dual carburator applications and hood scoops. This straight up design fetures an overall height of 4.75 inches.
The billet aluminum expansion tank and base have been professionally polished for a show car look.
Our Billet one-piece designed top expansion tank is unique to the industry and bolts to the base plate with an o-ring seal by 4 provided stainless steel cap screws. 1/4" push lock overflow fitting, stainless mounting bolts and gasket also provided.
Racers ourselves, We spent a tremendous amount of time making sure of the fit for the radiator cap, insuring the pressue seal and locking mechanism work as well as possible for extreme racing conditions.
