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

Wehrli Custom Fabrication is known for making well-built parts for Duramax trucks, and this thermostat housing kit is a prime example. If you're working on a 2006-2010 LBZ or LMM Duramax, this kit replaces the stock upper radiator hose and coolant return pipe with a more efficient, upward-flowing setup. This change not only updates the look of your engine bay but also makes accessing fuel system components on the driver's side much easier. It's also a key part if you're planning to install larger aftermarket turbochargers, especially those with a race cover style.

This kit is CNC machined from billet aluminum for a strong and lightweight housing, then finished in a durable semi-gloss black powder coat. It includes the necessary coolant pipe, silicone boots, and t-bolt clamps to complete the installation. The updated routing is designed to work with factory VGT-style turbochargers, and there's even an option available for twin CP3 fuel pump setups if your build requires it. This is a solid option for anyone looking to improve serviceability and make room for performance upgrades on their Duramax.
