TracTuff J Series Water Neck Flanges – V1

Description

You own an EG, EK, or DC2, and you’ve swapped in a J Series. Almost everything is right where you want it… except for that MONSTROSITY of a water neck staring back at you. The J Series billet water neck flanges were designed to be the premier water neck solution on the market! The flanges can be used as in conjunction with one of my remote mount swirl pots, or used to fabricate pretty much anything you can dream up.

The flanges are CNC machined from US-milled 6061 aluminum and incorporate -16 ORB outlet ports for each of the cylinder heads outlets as well as a -16 ORB port for the water pump inlet tube. The four bolt flange uses an OEM gasket (Not Included), and the rear has an o-ring groove. The front cylinder flange is also machined to uniquely hold the OEM water cross-over tube (pump inlet) and accept the OEM o-ring on the back side.

The four-bolt flange was redesigned in 2020 so that the water pump inlet tube holder would work with GM transmissions that are popular in the off-road world. The revision also ended up accommodating both generations of InlinePro J2K adapters.

NOTE:  The J Series Water Neck Flanges eliminate the thermostat, thermostat water bypass, ECT sensor, and fan switch. If you need any of those things, I recommend you reach out for guidance or consider one of my fabricated options. The water cross-over tube mount is unfortunately too low to work with scatter shields, so you’ll have to reach out to us so we can rethink your plumbing if you need to run one.
