  • TracTuff PRB/ PRC Water Neck Flange - V1

    $112.95 $102.95

    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 water bypass port and the hardware kit includes a hose fitting and a plug in the event you don't plan on connecting a bypass hose.
