The Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit for 2006-2010 LBZ/LMM 6.6L Duramax replaces the OEM upper radiator hose that normally crosses over the driver side valve cover as well as the coolant return pipe.

- Compatible with factory VGT style turbochargers
- Required for race cover style or SXE turbochargers being mounted in the valley
