GMC Duramax Thermostat Housing Kit - Wehrli - Dual CP3 - Bengal Silver - 06-10. Billet top outlet and upper coolant pipe solution for 2006-2010 LBZ/LMM trucks using WCFab Dual CP3s.

This kit replaces the OEM upper radiator hose over the driver-side valve cover and the coolant return pipe, routing coolant upward and forward from the thermostat. This improves access to driver-side fuel components and adds room for larger turbos. Works with dual alternators; not compatible with PPE dual fueler kits. Required for race-cover or SXE turbos in the valley; compatible with factory VGT turbos.
