Chevrolet Silverado Thermostat Housing Kit - Wehrli - Dual CP3 - Sparkle Granny Smith - `06-`10. A top-outlet billet housing and upper coolant pipe that re-routes the LBZ/LMM Duramax upper hose for cleaner routing and easier access.

Designed for 2006-2010 trucks, this kit replaces the OEM upper radiator hose that crosses the driver-side valve cover as well as the coolant return pipe, routing flow upward and forward from the thermostat. The layout improves access to driver-side fuel components and creates room for larger aftermarket turbochargers. Built around WCFAB Dual CP3 systems and compatible with dual alternators; not compatible with PPE dual fueler kits or 2006-2007 GMC Sierra. CNC-machined billet aluminum upper housing with Sparkle Granny Smith finish; compatible with factory VGT turbos and required when using race-cover or SXE turbos in the valley. Includes coolant pipe, silicone boots, and T-bolt clamps.
