This Product has been Discontinued

Fits: 2001-2005 GM LB7 & LLY w/ 6.6L Duramax 

The Sinister Diesel Coolant Hose Kit for the 2001-2005 Duramax (LB7/LLY) 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 fibres and 5mm silicone, which is twice the thickness of the 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.
