The 041-HSP Billet Thermostat Housing kit is designed for the 2006-2010 Chevrolet and GMC Duramax-equipped trucks.

**Benefits of the HSP Billet Thermostat Housing Kit:**

The HSP Billet Thermostat Housing kit offers enhanced performance and ease of installation for Chevrolet and GMC Duramax trucks. The routing of factory coolant lines in these trucks presents challenges in upgrading turbochargers and other performance accessories. Consequently, this kit serves as a valuable solution for enthusiasts seeking to modify their stock setups for increased power output.

**Key Features and Functionality:**

The HSP Billet Thermostat Housing kit is a billet-made component that simplifies installation and maintenance. It eliminates the factory coolant hose that crosses over the driver-side valve cover, providing ample space for future modifications such as turbocharger upgrades or the installation of dual CP3 pumps.

**Kit Contents:**
