    Hey guys,
    Wondering if I could get some help on this. I have a Jake Brake that I got from a local Used parts place for my Cummins L10. I never installed it and since got another truck with the M11 so I need the 411 Jake for that. So I am selling the one I have now which is a 404D. My question is someone asked me what years it will fit and if there was any limitations from when they switched the L10 from mechanical to computerized injection. Can anyone give me an answer on this. Dont want to steer this guy the wrong way. Thanks

    update.... The guy wrote me and said he has a 93 Ken with and ECM. I am thinking it might not fit cause my engine is a 94 L10 mechanical with STC. But not sure.
    The jakes are 404D P/N 017421 and 423
