    Posted by DE An on Nov 20th 2019

    The O Rings arrived on time, yet we never received them. Finally found out the our Post Office had a chemical spill, and it got on our package,making it undeliverable. This company worked with us to 2 Day ship new ones to us and refund our payment. Thanks Riffraff Diesel!!

    As usual, Clay has the best prices and the fastest shipping! Make sure and soak these in oil before installing!

    Injector O rings

    Posted by Unknown on Dec 19th 2018

    I was burning about 1 gallon of oil every 25 miles. I installed theses and I burn near no oil now. Took me about 11 hours to install but I'm a shade tree mechanic at best.
    BTW after running that much oil through my fuel system I needed to put new pre filters in and replace my fuel pump.

    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.
