    X code coils are 4000#

    F code rear leafs I'm still digging up.

    I'm assuming that we are talking about a 2005 - 2010 Super Duty?

    Yes 2006 f-250 super duty reg cab 5.4I engine is a 4000 rating strong enough for a snow plow. also on a super duty shouldnt the coils come with at least a 5200 rating
    My father inlaw bought this truck with a 7.6 boss plow on it for me to plow his buisness lots. I have been trying to learn things about plowing and this truck. From some of the posts ive read im concerned if this setup is okay. So far nothings broke or anything but im worried about long term. The front squats when plow is raised have 800 lbs ballast in bed

    Thanks for any replies
