Hey Bob, thanks for the information! For a weight distribution system that fits an 18,000 lbs trailer, you'll want the Blue Ox SwayPro Weight Distribution w/ Sway Control item # BXW2000. This system works with tongue weights from 1,500 - 2,000 lbs so it'll give you some range when loading up your trailer. This system comes with a 2-5/16" hitch ball. You'll need item # A-90 if you want to swap in a 2".
Please note you'll need to have space on your trailer's tongue 27" - 29" back from hitch ball to mount the chain hanger brackets.
The shank included with the SwayPro item # BXW2000 fits a 2-1/2" receiver and provides a 2" drop. For the tongue weight capacity you're needing you will need to purchase an extremely heavy duty shank for 4" - 5" of drop. The Gen-Y Torsion Weight Distribution Shank item # 325-GH-1302 is our only option for that high of a capacity. It fits a 2-1/2" receiver and provides up to a 7" drop. The bolt spacing is the same so you'll have no issues using it with the SwayPro item # BXW2000.
What kind of trailer do you have and does your 2500 have a 2-1/2" hitch receiver? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

Thank you for the detailed response yes the truck has a two and a half inch receiver I have a 26 ft Stacker 20K GVW although my truck supposed to not hold anything more than 16k. One question is the frame rails at 8 in coming off of the hitch that's 8 in high or thick however you would explain it will the sway bar connection fit to those pieces of Steel ?
