Fits 1500 GM/CHEV Diesel with Capless Diesel Filler, even 2024. This is NOT compatible with the 2500/3500 trucks. If the diesel filler has a screw-in cap, this set is NOT compatible with your truck.
The original Spin-Loc design for GM/CHEV was not compatible with the newer GM/CHEV trucks. We have since redesigned the body style of the Spin-Loc and it is now compatible with the Capless Diesel GM/CHEV trucks to the 2024 model year.
Get a deal by buying both an EZ-Loc and a Spin-Loc at the same time! Each combo purchase comes with the EZ-Loc cap, the Spin-Loc cap and one pair of Secure Keys with complimentary stainless steel key ring. Both caps have natural venting.
Additional keys can be purchased using the information from our Secure Keys page.

Fits my 2024 Chevy 1500 3.0 LZ0. The DEF cap is very secure. The fuel cap could be removed if a good amount of effort and prying force was applied by a bad actor, but it would likely break the green plastic fill port on the truck. These will definitely deter or delay a person from vandalizing your vehicle. Will prevent someone from putting DEF in the diesel port too, if you let someone borrow your truck. A great security option. Tip, I applied a thin wipe of grease to the fuel cap seal.
What a great idea. Looks great and easy assembly. You spend a lot of money for these trucks and it doesn’t come with a locking gas cap/lid. Ez-lock combo solves that problem. Great peace of mind………highly recommended.
Bought this for a 2026 GMC Sierra 1500 AT4. Looks and works absolutely amazing. It's a little tight to slide underneath the lip of the diesel side, but once you get the hang of it, it's extremely snug, which is perfect. I would have preferred the DEF knob to be blue to match things better, but it still works great.
