Fits: 2020 thru 2024 Chevy Silverado/GMC Sierra 1500 LM2/LZ0 Duramax Diesel

These caps might not increase your fuel economy but they will keep debris out of your fuel and DEF tanks.

The fuel cap was designed specifically to fit the LM2/LZ0 Duramax Diesel Trucks and fits snugly into the factory filler neck without hitting any of the flaps inside the filler neck. It comes with a strong o-ring seal to ensure a tight fit and keep contaminants out of your fuel tank. It is constructed of T6 6061 Aluminum and features a high quality O-ring that will last for many years to come. 

The DEF Cap is a high quality replacement for your factory cap, providing improved durability, functionality and a touch of style to your Duramax. A magnet is built into the cap for easy storage during fill ups.
