  1. Rollin' Coal Again! 5 Star Review

    Posted by on Jun 3rd 2018

    #6 injector was leaking past the lower o-ring seal causing massive amounts of smoke and knocking. Resealed all 8 injectors with these o-ring kits and the truck runs perfect again. Excellent product.

    Have not installed these rings yet, but coming from riffraff I'm sure they work perfectly as everything else I have ever gotten from them has worked out flawlessly.

  3. Just what is needed 5 Star Review

    Posted by on Apr 20th 2018

    Arrived faster than expected. Everything needed to replace my injector o-rings. I would like to review in 30K miles to follow up on how they performed.

  4. Great product 5 Star Review

    Your 7.3 power stroke injector replacement document was very helpful, might be nice to receive that with the order .
    I was lucky enough to stumble upon it on the web.

  8. The only injector o-rings you should use 5 Star Review

    Posted by on Nov 13th 2017

    These are by far the best injector o-rings available for the HEUI injectors in these motors. Don't cheap out and get aftermarket ones unless you want to do the job twice. By far the best value out there on these, and beats the price from Ford by a mile.

  9. Genuine Alliant O'Rings 5 Star Review

    Posted by on Nov 7th 2017

    Received nicely packed and quickly shipped...
    even included a cool Riff-Raff sticker also :)

    TIP: Use a curved pick to "walk" the o'rings on vs what you see all over the place on youtube were guys basically roll them on (there is a chance of rolling the o'ring that way) and If you do push and roll the o'rings on please check them to see that they are not rolled once they are in place.

  10. Perfect! 5 Star Review

    Posted by on Nov 6th 2017
