TracTuff J Series Water Neck Flanges
So you own an EG, EK, or DC2 and you've swapped in a J Series... almost everything is right where you want it! Everything except for that MONSTROSITY of a water neck starring back at you. The J Series billet water neck flanges were designed to be the premiere water neck solution on the market! The flanges can be used as is or used to fabricate pretty much anything you can dream up.
Flanges are machined from US milled 6061 aluminum. Both flanges incorporate -16 ORB outlet ports, the front uses the OEM MLS style gasket and the rear has been converted to an o-ring. The water cross-over tube mount (inlet) is machined to accept the OEM tube and o-ring on the back-side and also converts to a -16 ORB port on the front-side.
NOTE: If you are interested in a specific design, please email us at email@example.com. We also recommend designing the upper radiator hose so that there is droop/ give so the engines movement does not push/ pull on the radiator and fatigue any parts. Flanges have undergone a design change that allows them to be used with the popular J2K adapter kit as well as a few GM transmissions that previously did not work. The water cross-over tube mount is unfortunately to low to work with scatter shields.
