More than just a dress up piece, our water neck (thermostat housing) is CNC machined from solid billet aluminum finished to a mirror polish and includes stainless socket head mounting hardware. A simple and easy piece to install, our water neck will fit any 5.7 or 6.1 HEMI equipped vehicle including the new Challengers, Jeeps and Ram Trucks!

If you’ve tried to install an aftermarket water temperature gauge you will know what a headache it is with the modern HEMI’s. We’ve solved that problem as it is tapped to accept a standard 1/8” NPT water temperature sending unit. For late model applications this allows you to easily install a water temp gauge on any LX based vehicle (including the Challenger), Jeep or Ram Truck. For engine swaps, this makes your water temp gauge install a breeze. If you don’t want a gauge right now, we’ve included a socket head plug which gives you the flexibility to add it down the road.

This is a great dress up piece that eliminates the ugly black stamped steel piece your upper radiator hose attaches to. If you’re a fan of the modern HEMI, the XV Billet Water Neck is just for you.
