Hose Kit Features Stronger Silicone Construction

The 2011-2016 GM 6.6L Duramax is constructed at such a high level, but there are a few areas that show a little weakness overtime. One of these areas being the factory coolant hose "T" fittings. They are susceptible to cracking and causing coolant loss because they are made of cheaper plastic. The 2011-2016 GM 6.6L Duramax PPE Upper & Lower Coolant Hose Kit replaces this weak factory component with a much stronger and more durable 5mm thick silicone construction. You will immediately see the benefits of your coolant hose being able to handle higher pressures and temperatures experienced when pushing your GM Duramax to the limit.

Endures Higher Pressures and Temperatures

The 2011-2016 GM 6.6L Duramax PPE Upper & Lower Coolant Hose Kit is engineered to endure higher pressures and temperatures with its 4-ply heat-resistant internal fibers built into the silicone construction. The 5mm silicone construction of this coolant hose kit is twice as thick as the factory plastic and much stronger too. You are guaranteed to get a coolant hose system that is built for longevity and maximum functionality. When it comes to installation, you will attach the upper and lower hoses using the quick-connect ends, t-bolt clamps, and worm-drive fasteners. This combination of features creates the most precise and stable fit possible.
