    Excellent Upgrade

    Posted by Gary Rice on Apr 3rd 2024

    This was a no-brainer to upgrade, way cheaper than Ford wanted for the stock cover, and way nicer. Also the larger fill hole is so much better and easier to use than the stock one.

    Awesome cover!

    Perfect finish & fit, I love the larger fill hole and the fact of not having to worry about stripping out the allen head!

    Excellent Quality

    Way better quality than OEM, larger fill plug, and not to mention WAY less expensive the OEM. Best of all Made IN THE USA. TEAM RIFFRAFF for the WIN. Keep it up guys.

    Well Made

    Posted by James on May 16th 2023

    So much better made than stock, and the larger fill port also makes it much cleaner to fill with oil.

    It’s good

    Posted by Thomas Gray on Apr 10th 2023

    It’s good. Looks great but my only complaint is that it should come with a new o ring even if it raises the price. Or at least include an option to add an o ring so the guys like me that would think it already comes with one don’t get screwed and have to wait to instal.

    Was ok

    Posted by tyler bingamon on Oct 3rd 2022

    Looks good on the truck the bolts it comes with stripped out so I had to use my old one and hard to get a socket on the bolts that hold the plastic cover out

    Work of Art

    Posted by Jason D. on Sep 20th 2022

    Like all of Riffraff Diesels parts this is another work of art. Perfect fit, and they go the extra mile to include stainless hardware with it. The large fill port really comes in handy, fits a standard funnel and allowed me to fill the reservoir quickly and without making a mess like I usually do.
