TracTuff RBC/ RBB Billet Water Neck Assembly w/ Fill Port
A fabricated version of our RBC/ RBB Billet Water Neck with a radiator fill point. The flange and radiator cap bung are CNC machined from US Milled 6061-T6 aluminum with the absolute largest port you can fit within the restrictions of the OEM gasket and a 1/2" NPT accessory port. The outlet maintains the OEM position unless otherwise requested.
NOTE: Made to Order... usually a 2-3 day lead time - Contact before ordering if you need a firm ETA - If you are interested in a specific design that varies from this, please email us at firstname.lastname@example.org. 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. The filler tube is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side) for the traditional option and leaned forward 8° (intake side) for the lean option.
