    ford f350 sd door sticker states that i have x-code front and b-code rear. B-code is listed as 3000lbs. Is that normal?

    On the spring codes
    the second digit is going to be either "A" for a F250 or "B" for a
    In the Ford Spec book the rear spring is rated at 6830 lbs for SRW
    and 8250 for a DRW

    Hope that helps

    Don't confuse spring ratings with axle ratings. The rear axle on a SRW isn't limited by the springs, but the tires. It correlates with the individual tire ratings x 2.

    rmartin- 3,000 doesn't sound like anything that belongs on a 1-ton truck as far as Axle Weight Rating

    the rear springs are listed as combined (2) as 6830 min.
    But I think that's mis-leading

    But it's also listed as 2998 lbs rating per spring

    I guess what I've over looked is the Auxiliary (helper) spring
    there rated at 694 lbs each

    So you have 6830 (springs) + (2 x 694) Aux. = 8218 lbs

    That seems a little more like it

    id tag

    I was going by the tag on the door frame. Said the springs are XB. I wanted to know what the B stood for. I was told the 1st letter is the front code springs and the 2nd is the rear?
