Why would you need an HSP Billet Thermostat Housing kit?
The HSP Billet Thermostat Housing kit is a great addition to many trucks that are out there today. The way the Chevrolet and GMC Duramax trucks route the factory coolant lines makes it extremely difficult to upgrade turbochargers and many other performance accessories. Because of this when people are chasing the power and looking to change up their stock setups to something a little more radical the HSP Billet Thermostat Housing kit is exactly what they need.

What Does the HSP Billet Thermostat Housing kit do Differently?
First off let's look at the fact that our HSP Billet Thermostat Housing kit is exactly what we said, it's a billet piece of equipment that makes things leaps and bounds easier to use. Now let's go to what exactly do we make easier? The HSP Billet Thermostat Housing kit removes the factory coolant hose that crosses over the driver-side valve cover. The reason this is so crucial is that space is already so limited, and if you are looking to change up the turbo or needing to add in dual CP3 pumps then this is something that you are going to need.
