Chevrolet Silverado Thermostat Housing Kit - Wehrli Billet Upper Housing, Fine Texture Black, 06-10. A CNC-machined upgrade for 2006-2010 Duramax LBZ/LMM engines.

This kit replaces the upper radiator hose over the driver-side valve cover and the coolant return pipe, rerouting flow upward and forward from the thermostat. The new path improves access to driver-side fuel components and adds space for larger aftermarket turbos. Compatible with factory VGT; required for race-cover or SXE turbos in the valley. Includes coolant pipe, silicone boots, and T-bolt clamps. For dual CP3 or dual-alternator trucks, use WCF100424.
