Excellent products and best of all the fuel cap keeps dust out of the fuel tank. I live on a dirt road so dust is an issue for me. Fuel cap has a magnet inside so you can stick it to the side of the fender while fueling and not forget about it.

Love these.

It's irritating buying a 65,000 truck and they don't have caps for the diesel or DEF. This takes care of any possibility of any diesel accidentally getting into the DEF. The truck came with a crummy plastic plug for the DEF but the aluminum is much more professional than crummy plastic. For me, a must purchase!

Fit 2015/2017 RAM 1500 Ecodiesel

Very happy with these. The DEF cap was what I was after, so the diesel cap was a bonus. I was actually suprised by the strength of the magnet on the diesel cap. The DEF cap is not magnetic. They fill like a solid piece of billet aluminum. The power coat is even and glossy. The fit is spot on for both spouts.

great product, work well and provides an added degree of safety for the fill necks. You would think that when you pay 70K for a truck the manufacturer would give you a Dam cap.

Very well made and seem quite sturdy. It adds a nice "wow" factor when I open my fuel door. The green cap fits snugly into the fuel filler, so there is no worries of it vibrating loose. The DEF cap fits well, just like the fuel filler cap. No worries for either one vibrating loose.

Billet Aluminum Diesel and DEF caps

Both caps work well and look good. However, although it isn’t related to the product, the person who packaged this item felt the need to give the inside of the shipping bag a few good sprays of their finest gas station perfume. I can still smell it inside my home even hours later. Billet aluminum caps: five stars Shipping perfume: one star Bottom line, would recommend caps to a friend. Would not recommend perfume inside bag to anyone, even my ex-wife.

Fuel Cap

My RAM came with a plastic fuel cap cover which was sure to get lost so I grabbed this fuel cap. I like that its magnetic and has diesel on it to remind the fueler to use diesel. I didn't install the DEF cap and continue to use the plastic one that came on the truck.

Sexy thing

Oh yah!!! Not that my Dodge isn't sexy already but what's hiding behind my gas cap door makes it much sexier....to me anyway since I'm the only one that knows it there. Had the stock little yellow one on there for about 3 months and it was to ugly for me to look at. These are a nice little add on to any truck.

Perfect fit, color and size.

Both fit perfect. Look even better than the pictures. The magnet is awesome. The OEM little green cap over the diesel fuel line will get lost eventually and it let's funk get under it. These metal won't let in gunk and definitely won't fly away or get lost. I highly recommend. And the green diesel cap says "PLEASE Diesel Only". My wife and I got a good laugh when I opened these up and saw that. A great fit and funny saying like an old Snapple Tea lid.

Replacement for OEM

Got these for a new truck (2018) that I recently purchased. Wasn't too impressed with the plastic, milk jug like, cap that came with the truck for the Eco Diesel filler. So did some research and purchased these. Fit is perfect, price is reasonable, and quality is great. Like the magnet in the diesel cap which ensures that it isn't dropped somewhere while refueling. DEF cap is sturdy, quality construction, and screws on nicely. All in all, a great upgrade to the rather cheezy OEM parts.
