2013-2018 Cummins/EcoDiesel Revolver Billet Fuel & DEF Caps (66701)

These billet caps are more than a nice aesthetic upgrade. They feature a neodymium magnet that attaches to your fuel door, and beveled edges with a large grip for easy handling. Most importantly, they keep dirt and debris out of your tanks.

Part Number: 66701

Fits: 2013-2018 Dodge Ram HD 6.7L Cummins / 2018-2024 Dodge Ram 1500 3.0L EcoDiesel

• Prevents debris from entering filler necks
