    Brought truck back

    Posted by Nick on Sep 27th 2022

    Got 7 AD injectors and 1 AE injector. Truck was drinking about 8 quarts of oil per 500 miles, and ran really rough. Truck runs like new again and doesn't burn a drop of oil. Clay was great and helped me throughout the buying process. Will buy from Riffraff again when the time comes.

    These Injectors looked very well made and fit perfectly. Clay was very helpful through the whole replacement process. Quick to respond to simple uneducated questions and always knowledgeable and friendly.

    No more misfiring!

    I'm planning on keeping this truck for good, so I went with new instead of remans. Change out the glow plugs while you're in there.

    Posted by William on Sep 13th 2019

    I installed a new 'AD' Injector on my 2001 F-250 SD. The quality of their products are good and exactly what I needed to get my truck on the road again.

    Alliant Injectors in 02 F250

    Posted by David on Mar 22nd 2019

    Injectors are fine. I might not have tackled the job without RiffRaff's instructions and support. Easy to understand, clear, concise, supporting photos... RiffRaff is more than just a parts seller!
