    Did the 1 ton trucks come with a rear sway bar?

    If so, has anyone installed that sway bar on their .75 ton 'burb for towing?

    Will the 1 ton springs swap onto the .75 ton 'burb?

    FYI - this is not for me, I have a buddy who may want me to do this work to his 'burb and I want to give him the right answers.

    Thx

    my '83 1 ton did not have a factory rear sway bar. There is an aftermarket one available from JC whitney but I have no experience with it. I would advise against going with a 1 ton spring pack as the ride of that thick pack is horrendous. If he is just going to use it for towing I would go with one of those airbag systems.

    W.r.t. the springs, the springs will bolt up if they're both 56". Obviously if the Burb has 52"s (and I don't think it should, but I never remember) the one-ton's (which are almost definitely 56"s) won't fit ;)

    Interesting point about the big-honkin packs from the 1-tons; they won't flex and ride like crap, at least on an unloaded pickup. On a Burb that has more weight in the back they might be okay. :dunno: I have a set on my crewcab, but it's butt-heavy no matter what =))

    swaybar

    Only 2wd 1 ton's came with the factory rear sway bar dually and single tire in the 70s. From 81-91 they only were available on the 2wd duallys. Though I did put one on my 86 K30 and will be putting one on my 88 V30. They can only be mounted with the square style ubolts as they attach with the lower clam shell ubolt plate on the bottom. You do notice a difference positive: less sway...negative: a firmer ride.

    Hope this helps

    Actually, i have a rear sway bar from a SRW 2WD truck that had a 14ff with the standard round right side up U-bolts. Here are the pics of the brackets.

    Those are some rare parts.
    I tried a Hellwig rear sway bar on '85 Burb K10; she spit it out.:doah:

    My 86 3/4 4x4 ton had a rear swaybar. But it was on a semi-floating rear axle. I don't know if it would fit a FF axle
