  • TracTuff PRB/PRC Water Neck Flange - Race


    The recently updated "Race" version of our upper water neck for PRB/ PRC/ PPA cylinder heads now includes a raised lip that serves as an o-ring seat for those that want to use the -16 ORB threads for either a hose barb or AN fitting or as a generous spot for a fillet weld (for those that want to fabricate something custom). The flange incorporates an OEM o-ring grove machined into the backside and includes a Genuine Honda gasket and two stainless steel socket head bolts.
