whats the correct weight distributor bent bars?

8,800# GVWR TT means 900 to 1200 lbs tongue wieght. You need at least 1,000# but better would be 1,200# bars

My trailer has @1100# tongue weight. I may be overkill, but I use 1400# bars. Plenty of extra capacity, well under specs, and they work really well. Not a lot of extra cost either. You may also want to think about using 2 sway bars.

Typically the spring bars are sized up, just as those above are suggesting. It would be best to get an actual tongue weight of your TT so you aren't guessing.

1000# tongue weight I'd go with 1400# bars. But I'm guessing your tongue weight when loaded will be somewhere in the 600-800# range when fully loaded. In that case, I'd go with 1000# bars.
