I switched from 1,000lb bars to 1,500lb bars. Same truck and trailer. Made a huge positive difference. No negatives at all! At least in my case. I run about 1,200 of tongue weight. With the lighter bars I felt a lot of bounce between the truck and trailer. The larger bars stopped the vast majority of that. I run 9 free chains.
Very happy with the change, and I did speak with Blue Ox and they suggested it. Next will be a 2 1/2 version. Had a 1/2 ton truck when I got the Blue Ox, now in a 3/4 ton. Would love to get rid of any play there.
