TracTuff PRB/ PRC Billet Water Neck w/ Swirl Tank V1SR


A version of the OG... this piece has simply been moved back to the rear of the cylinder head. 

Our billet water neck incorporates an OEM o-ring grove on the mating surface and a 1/2" NPT water bypass port. All billet parts are CNC machined from US milled 6061 aluminum. The radiator cap bung uses the larger domestic style cap for the largest opening and huge selection of cap offerings. 

NOTE: Made to Order... usually a 2-3 day lead time - Contact for ETA - The exhaust cam sensor must be swapped to the version that points up in order to  clear the tank. If you are interested in a specific design that varies from this, please email us at If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. Tank is welded so that it sits level when bolted to an engine with a 15° lean back (exhaust side).

1/1/19 Update: Due to the stress placed on the brackets/ braces, a plinth can be added to distribute the load and increase strength.
