    1999 K1500 Suburban towing capacity

    Does anybody know what the towing capacity would be on a 1999 k1500 suburban with 350 engine and 373 gear ? I don't have the manual and the sticker on the drivers door is missing. I have been told 6000 lbs. I think that is to low. My 2002 trailblazer can pull 5600 lbs.

    I had a 97 Tahoe with the same transmission as is in your truck. I made two trips towing a box trailer that was probably 8,000. Smoked a transmission not long after each one....

    RIP Sonic (Warning ugly photos)

    Take a look in the above thread. I would not tow more than 6500lbs with a burb. It just does not have the abillity to do so safe. And if possible, run a good elec over hyd. brake setup on the trailer.

    The problem with a Suburban, is that we never tow with the TRUCK empty. You then have to worry about the COMBINED weigh rating. Tow/weight ratings are calculated with an enpty truck, and no cargo.

    2 adults, 2 kids, luggage, dog, coolers, etc etc. You will max out that Sub even towing 5500#. Also, don't believe anything you read on what your rig weighs unless you are reading a scale ticket at a truckstop.

    IF, you are going to tow with this setup, I HIGHLY recommend Firestone or AirLift aftermarket air springs, as the factory coil springs suck for towing stability.

    correction,,front are tortion and the rear are leaf springs..if he adds one leaf it will be good for 1500 lbs of weight..
