Maximum bumber gross weight?
 

Hello everyone, I am new to this site, but by looking around you all seem to know exactly what going on all the time. I need to know what the maximum towing capacity of the bumper for my 1992 Chevy cheyanne truck. It is a 3/4 ton with a step bumper. I put a 2" ball onto the bumper and i need to know what hte max is I can pull will that ball? I can't seem to find this info anywhere else, please help me out with this if it's at all possible? Also i would appreciate it if anyone could tell me about hooking an electric power brake booster? Thank you all for your help. I am also looking to buy a cheap hitch for the same truck, it's 2 wheel drive with a full size bed. Thanks again

Thanks
Jeremy

If it is a stock bumper, it is stamped right on it.
