Sinister Diesel 11-16 GM Duramax 6.6L LML Radiator Pipe

Sinister Diesel is known for making tough parts for diesel trucks, and this radiator pipe is no different. If you're working on a 2011-2016 Chevy or GMC 2500 or 3500 with the 6.6L Duramax LML engine, you know the factory rubber hoses can get brittle and crack over time, leading to cooling system issues. This kit replaces those weak points with a much more robust setup.

The pipe itself is made from 6061 aluminum, which resists abrasion and cracking far better than rubber. It's precision mandrel bent to fit just like the original, so you won't have any trouble getting it installed. To handle the heat and pressure, it comes with four-ply silicone boots that are rated up to 400psi, and they even have the Sinister Diesel logo on them. Plus, it's finished in a sharp Sinister Blue powder coat that really cleans up the look of your engine bay.

This kit includes the aluminum pipe, the silicone boots, and stainless steel hose clamps, so you'll have everything you need to swap out your old, worn-out radiator hoses for a more reliable and better-looking setup.
