TracTuff RBC/ RBB Billet Water Neck

TracTuff RBC/ RBB Billet Water Neck


Our Billet Water Neck for the K24A2, K24A4, K24A8, and K20Z3 offers the cleanest way to eliminate the bulk typically found with the OEM units and works great by itself or the base for custom solutions such as a radiator fill point and swirl tank. 

CNC machined from US Milled 6061-T6 aluminum with a -16 ORB outlet, which is the absolute largest port you can fit within the restrictions of the OEM gasket and a 1/2" NPT accessory port.

NOTE: If you are looking for a neck to replace the OEM unit, please purchase this OEM Replacement
