Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit - Gloss Black

Wehrli Custom Fab is known for making well-built performance parts for diesel trucks, and this thermostat housing kit for your 2006-2010 Duramax LBZ or LMM is a prime example. This kit replaces the stock upper radiator hose and coolant return pipe with a new, upward-facing coolant outlet and a dedicated coolant pipe. This updated routing not only cleans up the engine bay appearance but also makes accessing fuel system components on the driver's side much easier. It's a common upgrade for those looking to install larger aftermarket turbochargers, especially race cover or SXE style turbos, as it provides the necessary clearance.

Crafted from CNC machined billet aluminum, this housing is built to last and finished in a sleek gloss black powder coat that resists corrosion and looks sharp. The kit includes the coolant pipe, silicone boots, and t-bolt clamps needed for installation. It’s designed to work with factory VGT-style turbochargers, offering a practical solution for engine bay modifications. This kit fits a range of Duramax trucks, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD, making it a versatile upgrade for many diesel owners.

If you're working on a custom turbo setup or simply want to improve access and aesthetics in your LBZ or LMM Duramax engine bay, this Wehrli thermostat housing kit is a solid option. It addresses common clearance issues and simplifies routing for a cleaner, more functional engine compartment.
