    Great product. Add a little oil to the seal and lock tight the threads and it will go right in and seal perfect.

    Quality stuff and great service

    I am in the process of rebuilding my 7.3 and i got to the rail plugs. Riff Raff was the easy first choice and i got them super speedy and great quality. Riff Raff also upped their sticker game with the new rubber emblems. Super impressed!

    Excellent products and service

    Posted by Dante on Feb 20th 2017

    I was unhappy when these o-rings did not arrive a week after they were expected. The USPS claimed the package was delivered to my mailbox and was very unhelpful. I turned to Riffraff for guidance and was informed that the package was not insured, however they stepped up and sent me a replacement order at no charge. I'm not sure they would have done this on a larger order, but I'm very impressed nonetheless. Excellent affordable products and exceptional customer service.

    Oil leak

    Posted by John on Mar 17th 2016

    I had a bad oil leak on the back of the head from the plug. Replaced it with this o-ring and it was gone. Fast shipping and a great price. Definitely buy more from here.

    These seals were perfect replacement. I used them while I had my motor out of the truck. Was a convenient time to change them. Highly recommend.
