TracTuff PRB/ PRC Billet Water Neck

TracTuff PRB/ PRC Billet Water Neck


The popularity of our RBC/ RBB water bypass adapter brought a lot of requests for us to produce an upper water neck for PRB/ PRC cylinder heads and we listened! CNC machined from US milled 6061 aluminum; our water neck incorporates an OEM o-ring grove on the mating surface side, -16 ORB (O-Ring Boss) threads for the outlet and a 1/2" NPT port for the water bypass. 

NOTE: The billet neck has a 1/2" NPT port on the bottom side so you can choose to reconnect the factory water bypass hose (hose fitting option) or you can delete it (plug option), I recommend you keep it but its entirely up to you!
