While these caps might not increase your fuel economy or power output, they keep debris out of your fuel and DEF tanks and look good doing it.
Our premium diesel and DEF fill caps for 2019-Current RAMs are machined from 6061 anodized billet aluminum for durability. Beveled edges and large grip make them easy to use even with the biggest hands.
Both caps feature a strong neodymium magnet to conveniently attach them to your fuel door while at the pump. Never lose your cap again!
Just twist to lock them in place. Their included o-rings will prevent dirt, debris, and anything else from falling into your fuel or DEF system.

Banks Truck
"Thank you Gale I never truster the no fuel cap in my 3500RAM now thanks to you I can relax. Thank you."
Simply perfect.
"The most over engineered overbuilt fuel and def cap ever created and I love every single bit of it. These things work exactly how you would hope and look just as good. Odd how excited I was when I opened the box. Banks killed it yet again."
Nice product
"As always banks comes through with nice products for the rams. Great design very easy to grab a hold of even with arthritis Thanks again banks"
Small Upgrade, Big Difference
"These Banks billet diesel and DEF caps are a simple upgrade that makes a big difference. The quality and finish are top-notch, they look way better than the cheap OEM green flimsy plastic cap. The green and blue anodized aluminum really stands out and gives your truck a clean, custom look every time you pop the fuel door. While they don’t add any horsepower, they do something just as important, they seal tight and keep out dust, dirt, and moisture that can get into your fuel or DEF system. The fit is perfect, and you can feel how solid they are compared to the factory caps. Overall, this is one of those small upgrades that shows real attention to detail. Great look, great protection, and definitely worth it."
