Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit For Dual CP3 - Gloss Black

If you're working on the fuel system of your 2006-2010 Duramax LBZ or LMM, especially if you're installing a Dual CP3 setup, this Wehrli Custom Fabrication Thermostat Housing Kit is a smart move. This kit replaces the stock upper radiator hose and coolant return pipe with a new, upward-facing coolant outlet. This change in routing is key because it significantly opens up the driver's side of the engine bay, giving you much better access to your fuel system components. It also clears the way for larger aftermarket turbochargers, particularly those with a race cover or SXE style, and updates the overall look of your engine compartment.

This kit is CNC machined from billet aluminum for a strong, well-built housing that's finished in a sleek gloss black. It's designed specifically to work with Wehrli's Dual CP3 kits and also plays nice with dual alternator setups. While it's compatible with factory VGT-style turbochargers, it's important to note that it's not designed to work with PPE dual fueler kits. The kit comes complete with the coolant pipe, silicone boots, and t-bolt clamps you'll need for installation, making it a comprehensive solution for your cooling and fuel system upgrade.

This Wehrli thermostat housing kit is a solid option for a range of GM trucks, including models like the Chevrolet Silverado 2500 HD and 3500 HD, and GMC Sierra 2500 HD and 3500 HD from 2006 through 2010. It's a necessary component if you're fitting a race cover or SXE turbocharger in the valley, and it offers a cleaner, more organized look under the hood.
