2013-2019 Dodge Ram Diesel Magnetic Billet Aluminum Fuel Cap & DEF Cap Combo


Tired of the lack of a quality gas cap on your expensive Ram Diesel truck?

What about the cheap looking plastic cap?

Well here is the gas and cap combo that you've been looking for.

As good looking as they are functional, this combo will keep dirt and debris out of the fuel system while making the other owners jealous.

These are the caps that should have been included stock.

The Green Diesel Fuel Cap also has a magnet on the bottom!

Keep your engine running smoothly with an anodized green aluminum Diesel fuel cap and blue DEF cap that is far more reliable and effective than the cheap red plastic cap that the manufacturer provides and your plastic diesel exhaust fluid cover.

These will fit the 2013-2019 Dodge ram 1500, 2500, and 3500 Diesel trucks 

This kit comes with both caps and FREE SHIPPING IN THE USA!

    Good quality product.
    Had to purchase a thicker o ring which is understandable due to the factory filler neck being made of plastic and there is going to be size discrepancy between each individual unit.

    Fuel and def caps

    Posted by Mike Fisher on 7th Oct 2019

    The caps look well made. The Def cap fit like a glove. The diesel fuel cap was not as good a fit as I had hoped for. Leaving me concerned of possible water contamination. I Informed the company over the weekend about my concerns. And a response was quick with a new one on it’s way. Thank you for your great customer service. Will let you know how the new one fits

    Great Fitment, Great Look

    Diesel cap had a great friction fit, and the DEF cap screws in perfectly. I liked how it reused the OEM plastic ring. Overall, great little mod for an area that Ram overlooked.

    This came across on a Facebook Ad, so was skeptical, but other reviews where good so thought I would give it a try and am pleased with the product. A Trooper noticed it while at the pumps, and wants one for his patrol car, not sure if they make one for a gas vehicle but he was going to look into it! Many dirt roads where I live and an affordable peace of mind with the seal to try and keep a little more dust from the fuel.
