Eliminate the obstructive factory coolant hose routing on your 2001-2005 GM 6.6L Duramax with the HSP LB7/LLY Billet Thermostat Housing Kit With Coolant Return. With a CNC billet aluminum construction, this upper housing thermostat kit makes extra room for larger drop-in turbos in the valley as well as dual cp3 setups by eliminating the factory coolant hose that crosses over the driver side valve cover. HSP utilizes reinforced silicone boots and a hard tube for added strength versus the factory rubber hose. This kit features provisions to return coolant from the turbocharger. 

FEATURES:
  • Reinforced Silicone Boots
  • Includes Installation Hardware
  • Allows Room For Dual CP3 Kits
  • CNC Billet Aluminum Upper Thermostat Housing
  • Improved Design Allows Easier Access To Driver Valve Cover
Note: For use with stock or drop-in replacement VGT turbos.
