Fits: 2015 thru 2018 Chevy Silverado High Country 2500HD/3500HD LML/L5P Duramax Diesel

*High Country models ONLY!*

OEM GM winter cover for your truck during the winter months. Duramax engines utilize two thermostats and during cold weather, the engine may never get up to the proper operating temperature. These covers will help maintain proper engine operating temperature which will ensure faster warm ups and better fuel economy. Easy installation, no drilling required.
