TracTuff PRB/ PRC Billet Water Neck w/ Fill Port V2
Welcome the V2 PRB/ PRC Billet Filler Neck!! Took a little while for this new concept to register... but better late than never, right?
Just my standard PRB/ PRC water neck with a borrowed second hole from the likes of the RWD version; allowing for the hose to come out of the face or the side... and the filler to come out of the opposite. Bound to be the top pick for the discriminating customer that wants the best! No crooked filler position, no hard to reach radiator cap, and best of all... no Lego like construction with multiple places to leak from!
The filler neck starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint as well as a 1/2" NPT water bypass port and machined o-ring groove for the OEM gasket. Chose from a list of options to make the product as unique as your project; including sensor ports for oem or aftermarket sensors, hose connection type and radiator cap bung type.
All billet parts are CNC machined from US milled 6061 aluminum. The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap.
NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at email@example.com. 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 is welded so that it sits level when bolted to an engine with a 15° lean backwards (exhaust side).
