SDP LML Coolant Crossover Pipe 2011-2016 Duramax

This is an upgrade to the factory upper coolant hose going to the radiator. We make ours out of 304 Stainless Steel so you can be worry free of rust and deforming as you would get from either steel or aluminum. We can add 1/8"NPT bungs as necessary so that you can monitor temp or pressure with an auxiliary gauge.
