TracTuff sells a lot of billet water necks and DIY swirl tanks. Occasionally they build combos that get a lot of attention on social media and send a flood of DM's, PM's, and email's their way... this here is one of them. TracTuff can duplicate this combo or sell you all the pieces so you can do it yourself. 

Their billet water neck is machined from US milled 6061 aluminum and incorporates an OEM o-ring grove on the mating surface. The swirl tank lid and bottom are also machined from US milled 6061 aluminum with a step that fits perfectly inside the 3" tubing. The radiator cap bung uses the larger domestic style cap for the largest opening and huge selection of cap offerings. TracTuff either use 1-1/4" or 1-3/8" tubing depending on the type of connection you request and they can add ECT and/ or Temp Gauge bungs on request.


Note: ECT sensor must be moved to the swirl tank due to design. ECT port on cylinder head must be plugged and intake camshaft sensor must be swapped for an angled version. We also recommend the stiffest mounts possible and/ or upper radiator brackets that allow the radiator to move with the engine.
