Loc-Sure for 2023 FORD Diesel

Fits 2023 FORD Superduty trucks with the Powerstroke Diesel engines with diesel pipes as pictured (painted black inside). If your 2023 model Powerstroke diesel truck has a bare stainless steel diesel filler pipe, you will need to order the set we sell for the 2021-22 model year Powerstroke trucks. CHECK CAREFULLY!  
This is NOT compatible with the F150s or earlier model year trucks.  
There is select forward compatibility with the 2024-2025 model years; some trucks are compatible with the kits out of the bag, some need a seal kit for the diesel caps.  If you want to install this on your 2024-2025 Ford, please include a note with your order so that the seal kit can be included. 
Some customers report difficulty operating the caps. Please call customer service in case this happens to you. 
 
Each Loc-Sure purchase comes with the Loc-Sure cap and one pair of Secure Keys with complimentary stainless steel key ring.  The Loc-Sure has natural venting. Additional keys can be purchased using the information from our Secure Keys page.
