Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit For Dual CP3 - WCFab Grey

If you're working on the fuel system of your 2006-2010 Duramax LBZ or LMM truck, 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, rerouting coolant flow upwards and forward. This change significantly improves access to the driver-side fuel system components, which can be a tight squeeze on these trucks. It also clears the way for larger aftermarket turbochargers, particularly those with a race cover or SXE style, and even works with dual alternator setups.

Crafted from CNC-machined billet aluminum, this thermostat housing is built solid. The kit includes the coolant pipe, silicone boots, and t-bolt clamps needed for installation. By updating the coolant routing, you not only gain practical access for modifications but also give your engine bay a cleaner, more modern look. This kit is designed to work with factory VGT-style turbochargers, offering a versatile upgrade for various performance builds. It's important to note that while this kit is compatible with dual alternator setups, it is not compatible with PPE dual fueler kits.

This Wehrli thermostat housing kit is a well-built component that addresses common access issues when modifying the fuel system and turbo setup on your Duramax. It's a necessary piece for many performance builds, especially those aiming for increased power and easier maintenance. Ensure you check the fitment details to confirm it's the right choice for your specific truck configuration.
