GMC Duramax LBZ Thermostat Housing Kit - Wehrli - Dual CP3 - Bronze Chrome - 06-10. A top-outlet billet thermostat housing and upper coolant pipe for 2006–2010 LBZ/LMM trucks running WCFab Dual CP3.

This kit replaces the OEM upper radiator hose over the driver side valve cover and the coolant return pipe. By rerouting coolant upward and forward from the thermostat, it improves access to driver-side fuel system components and frees space for larger aftermarket turbochargers. The CNC-machined billet aluminum upper housing is finished in Bronze Chrome and the assembly supports dual alternator setups.
