Fits 2013-2018 RAM 6.7L Cummins Turbo Diesel and 2014-2018 RAM 3.0L Ecodiesel.

The EZ-Loc is the only locking/tamper-resistant capless fuel system cap on the market for Dodge Ram diesels. Well-meaning friends or neighbors who borrow the vehicle can be prevented from accidentally filling up on gasoline (we all know it happens). Unscrupulous individuals can also be blocked from access to funnel unwanted matter into your fuel system without your knowledge. How? Because you have the key.
 
The EZ-Loc works on the parent company's Secure Screw system which has been tested and approved by military and other secure facilities as a low-level human secure system. Bottom line: The EZ-Loc is locked until you open it with the key, or the whole top of your fuel filler neck is cut off.
 
Each EZ-Loc purchase comes with the EZ-Loc cap and a pair of Secure Keys with complimentary stainless steel key ring. Additional keys can be purchased using the information from our Secure Keys page.
 
BEM Auto's EZ-Loc main components are fully machined from aluminum bars at the BEM Auto factory. All aluminum tops are finished in a generic green anodized surface etched to identify the assembled unit as a diesel only cap, and the bottoms in flat black anodize.
