    High Quality

    Don't bother with any brand of o-rings other than Alliant (You'll regret it sooner or later....most likely sooner.). Great quality and fast shipping as usual!

    Rollin' Coal Again!

    #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.

    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.

    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.

    The only injector o-rings you should use

    Posted by Nate 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.
