Chevrolet Silverado Thermostat Housing Kit - Wehrli - Billet, Custom Powder Coat - Gun Metal - ’06–’10. For 2006–2010 Duramax LBZ/LMM Silverado, it replaces the factory upper hose and return pipe with a billet top‑outlet assembly.

Upward, forward routing from the thermostat improves access to driver‑side fuel components and creates room for larger aftermarket turbos. Compatible with factory VGT units and required for race‑cover or SXE turbos mounted in the valley. Offered for single CP3 (WCF100420) or twin CP3/dual‑alternator setups (WCF100424). Replaces GM 19330105, 15792824, 25833204, 97361881. Not compatible with 2006–2007 GMC Sierra.
