TracTuff J Series Water Neck Flanges

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. You now have a solution!!

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 (just look at our K Series options). 

Flanges are machined from US milled 6061 aluminum. The rear flange incorporates an o-ring grove while the front retains the OEM gasket. The water cross-over tube mount is machined to accept the OEM o-ring on the back-side and converts to a -16 ORB port on the front-side. 

NOTE: If you are interested in a specific design, please email us at 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.
