TracTuff Billet Water Neck Rear Wheel Drive K Swap - RBB


The introduction of the RWD version of the RBB/ RBC style water neck left a lot to be wanted; it was a slam dunk for those interested in running AN lines, but left the end-user with the headache of finding a traditional hose that would work. I've seen combinations of multiple radiator hoses joined with numerous clamps or rigid aluminium tubing that has been fabricated to navigate the engine bay; which is a great option but costly and not something everyone can do.

With the help of Pit Garage I and am happy to announce that I now have a true solution! Originally modeled after the S2000 manifold attached to the k series head via an adapter plate, a jig was made, and adjusted to fit both the S2000 manifold as well as the Skunk2 Ultra Street manifold with the plenum flipped. The end of the tube is VERY similar to the OEM S2000 water neck position so the S2000 upper radiator hose is now able to be retained and may be useful in a number of other RWD K Series applications.

This is likely to be the highest point in the cooling system so we have added the option of a bleed port for those interested. 

NOTE: Made to Order - Usually 1-2 day lead but contact for ETA - If you are interested in a specific design, say a fill point version of this or a swirl tank, we can make on request. Please email for additional info. The tube is welded so that it sits as the OEM neck does when bolted to an engine with a 15° lean to the passenger side (exhaust side).
