HSP 040-HSP Billet Coolant Thermostat Housing Kit

The HSP 040-HSP Billet Coolant One-Piece Thermostat Housing Kit replaces the factory upper thermostat housing on your GM 6.6 Duramax LB7/LLY. The factory coolant line routing on Duramax engines makes adding performance upgrades or changing to a different valley-based turbo that has no cooling provisions extremely difficult. This billet thermostat housing and tube eliminates the factory coolant hose that crosses over the driver's side valve cover. This allows more room for aftermarket turbo systems and fuel components. The HSP Billet Thermostat Housing Kit also allows you the extra room to run dual CP3 Kits. To further enhance the look under the hood of your truck this kit is available in multiple powder coat finishes.

Features:

• Allows Room To Install Dual CP3 Pump Kits
• Multiple Color Options And Custom Options Available
• Allows For Added Room For Aftermarket Turbochargers
• CNC Machined Billet Aluminum 1-Piece Thermostat Housing
• Powder-Coated Hard Tube To Improve The Look Of The Engine Bay
• Easier Access To Fuel System Components On Drivers Side Valve Cover
