Chevrolet Duramax Thermostat Housing Kit - Wehrli - Dual CP3 - Bengal Gray - ‘06–’10. Billet top‑outlet housing and upper coolant pipe that re‑routes LBZ/LMM coolant for a cleaner, more serviceable layout.

Engineered for WCFab Dual CP3 builds, the upward/forward path from the thermostat clears the driver‑side fuel area and makes space around the valley. Works with factory VGT chargers and dual alternators. Kit includes coolant pipe, silicone boots, and T‑bolt clamps. Not compatible with PPE Dual Fueler kits or 2006–2007 GMC Sierra. Replaces GM 19330105, 15792824, 25833204, 97361881.
