Amazing!
Super easy install looks way better than stock. Way heavier duty than the flimsy orange plastic peice that came with the truck. The colors look great and add a really nice subtle touch. The DEF cap is also medal and heavy duty and fits perfectly. I would definitely recommend this.

Good Replacement, Perfect Fit (2018 Ram 2500)
Fits perfectly, good quality and came with an extra seal, thank you very much for the needed replacement; 2018 Ram 2500

Great find
Glad I found this. My only problem with the newer Chevy trucks is that, instead of a fuel cap, they have a spring-loaded flap. Probably not an issue but I'm wary of debris getting in there. This cap was a perfect fit and eases my worries. The o-ring on it could be a little snugger but at least it comes with a spare.

It’s a strong durable gas cap great buy
Definitely happy with my purchase. This replaced a plastic one that would fly off the truck bed. These are definitely awesome and stay in place. No corrosion around the cap. Easy to get off and put back on. Much more efficient and durable gas cap for my diesel truck. It’s a great value for the quality. It’s strong in staying in magnetic strength is awesome. So happy I got these and can’t believe this truck that cost so much came with a plastic gas cap?? That’s just weird and unbelievable for the cost of the truck I would have expected this kind of cap. Highly recommend if ya have a plastic one. You won’t be disappointed and thank you

Recommend.
Got as a Christmas gift for a Diesel owner in the family. Very impressed by the weight magnetic for the fuel and def caps, makes a solid seal but it easy to remove when filling up.

Works well, keeps the dirt and water out of the tank on a cap-less system. Fits a GM 1500 w/LZ0.

Product was nice looking and appeared good quality but the diesel cap is nowheres close to fitting. Way too small for my 2014 Ram 3500. Every 4th Gen Cummins Ram I have seen have the same design so I can't see fitting any of those. The DEF cap does it and twist-lock in but I prefer my original plastic cap since it has the plastic retaining strap . Hard to believe so many positive reviews. Complete waste of money for something that now hangs out in one of my junk drawers in garage. It may fit eco-diesel trucks but not the cummins.
