    I've got an 83 Suburban 3/4 ton 4x4 and I was wondering what all it had from the factory concerning smog/emmisions?!?!

    To my knowledge it didn't come factory with cat's so I wondered what else it was missing. I've got something that looks like fuel lines and wiring dangling from behind the passenger rear wheel under the back quarter panel :doah: and don't know what THAT is either.

    FYI....I'm in NC not the soviet republik of Kali, so anything older than 95 doesn't get the sniffer, only a safety inspection

    each one is different, all depends on many factors including where it was built for and at, and GVRW and drivetrain combo and so forth

    theres an emission label under the hood on the rad support or on the air cleaner

    if its over 8200 GVW then its probably only got TCS and possibly AIR

    no cats, no EGR, or ESC/EST

    the heavier rigs didnt get very much for emissions equipment in 48 states anyways

    IL is changing to 95 and older also, but they only test around the big city anyways, and not out here in cornfields no where down state, cept possibly near St Louis maybe

    good luck
