Factory coolant routing on LBZ and LMM trucks severely limits access for performance modifications, especially with upgraded valley turbos and dual CP3 systems. The HSP Forward Facing Thermostat Housing Kit removes these barriers, making your build simpler. What Makes It Different? Unlike the stock unit, this kit eliminates the coolant hose crossing over the driver-side valve cover, opening up room for turbo systems, custom fab work, and fuel components. It’s CNC-machined, powder coated for durability, and designed to improve clearance and serviceability while cleaning up the engine bay. Overview CNC-machined aluminum thermostat upper housing Increased clearance for aftermarket turbochargers Improved access to driver-side fuel system components Powder-coated hard tube for a cleaner engine bay Allows fitment of dual CP3 pump kits Multiple color and custom finish options available Fitment LBZ: 2006–2007 (VIN Code 2 or D) LMM: 2007.5–2010 (VIN Code 6) How do people know the VIN code? Engine code is dictated by the 8th character of the VIN number. The 10th character is the year of the truck.
