Okay but not perfect and a rip off price that is outrageous for such items… Ridiculous in my opinion… It appears that the seller/manufacturing party is taking advantage of such items and inflated the price unreasonably to a point of rip off in my opinion… Sorry but that is what I am thinking paying $140+ for these two aluminum items, which still have flaws in my opinion again.

Fits perfectly on my 2024 Chevy Silverado 1500 trail boss 3.0l duramax. Great design which provides ton of protection for your truck. Peace of mind is worth every penny IMO.

Had to return it. The description states it’s for a 2021 Chevy 1500 Silverado Duromax diesel. Wrong description. Does not fit. No one has this item available for the 1500. Disappointing🥲

Well built pieces, but I am only using the diesel cap. If there was only one thing to change, I’d recommend making the DEF cap blue like it is already on the truck! Still really good quality though.

Works great so far. Just sucks that they started making vehicles without gas caps so anyone can put something in your tank in just a few seconds and since this is new and the only one that’s made for the new fuel tank cap less spot that I know of right now. They are a lot more in cost than a regular key locking gas cap. But helps keep my vehicle safer from nowadays people that just want to cause problems and trouble for others. Overall great quality, just high price but worth it to keep from getting your motor messed up from someone adding something to your tank without your knowing.
