TracTuff PR3 Billet Water Neck w/ Swirl Tank

TracTuff PR3 Billet Water Neck w/ Swirl Tank

$399.95 $329.95

Our billet water neck is machined from US milled 6061 aluminum and incorporates an o-ring grove on the mating surface and a simple and classy TracTuff logo. 

The swirl tank lid and bottom are also machined from US milled 6061 aluminum with a step that fits perfectly inside our 3" tubing. The radiator cap bung uses the larger domestic style cap for the largest opening and huge selection of cap offerings. We either use 1-1/4" or 1-3/8" tubing depending on the type of hose connection and we can add Temp Gauge bungs on request. 

The PR3 design shown also incorporates a brace that helps support the cantilevered weight from taxing the weld at the water neck flange as well as fight off the push and pull affect associated with engine movement. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at We also recommend designing the upper radiator hose so that there is droop/ give so the engines movement does not push/ pull on the radiator and fatigue any parts.
