Wehrli Custom Fab's dual-CP3 top-outlet billet thermostat housing and upper coolant pipe kit for 2006–2010 Duramax LBZ/LMM replaces the OEM crossover hose and coolant return pipe, routing coolant upward and forward to free space around the driver-side fuel system and accommodate larger turbos. Finished in red, the kit includes the coolant pipe, silicone boots and t-bolt clamps and is CNC-machined for compatibility with factory VGT-style turbochargers.
