The Sinister Diesel Coolant Hose Kit for the 2006-2010 Duramax (LBZ/LMM) is a perfect way to ensure your cooling system is reliable for years to come. Factory hoses and T-Fittings are prone to cracking or failure, especially when pushed to their limits. Our Coolant Hose Kit is made from 4-ply heat resistant internal fibers and 5mm silicone, which is twice the thickness of factory hose. T-Fittings are TIG welded, 304 Stainless Steel to eliminate failure points. The quick-connect/disconnect end is made from billet aluminum and 304 Stainless Steel. T-Bolt clamps and worm-drive fasteners are used for a better than factory fit. Our hoses are finished in our Signature Sinister Blue. 


  • Direct Bolt-on upgrade (No modifications needed)
  • CNC Aluminum and Stainless Steel construction
  • 4-ply 5mm Silicone Hoses (Twice the thickness of OEM)
  • Quick Disconnect/Connect Hose Ends
