Fits: 2011-2016 GM w/ 6.6L Duramax
This is an upgrade to the factory upper coolant hose going to the radiator by SDP. Tey make them out of 304 Stainless Steel so you can be worry free of rust and deforming as you would get from either steel or aluminum. They can add 1/8"NPT bungs as necessary so that you can monitor temp or pressure with an auxiliary gauge.
