Heavy Duty Silicone Radiator Hose Kit For 01-05 Chevy GMC Duramax 6.6L – Blue, 1-Year Warranty

Upgrade your cooling system with this heavy-duty silicone radiator hose kit from Mammoth Performance.

It’s designed for 2001-2005 Chevy and GMC trucks with the Duramax 6.6L diesel.

The hoses are made from high-quality silicone in a bright blue color—so they look good and perform even better.

They’re more durable than stock rubber hoses, resisting heat, ozone, and coolant additives.

This is a direct replacement kit, meaning it bolts right in with no modifications.

It includes all the hoses you need for the radiator and cooling system.

Manufacturer part number is CC660106BL, and it crosses to OEM numbers like 26397X and 88920368.

Backed by a 1-year warranty from Mammoth, so you’re covered if anything goes wrong.

Whether you’re building a performance rig or just replacing old, cracked hoses, this kit is a solid investment.

The blue color adds a little flair under the hood, too.
