I use 1000# spring bars. I chose that size because the car weighs 4400# with a long deck and a longer than 'normal' hitch ball shank. When the bars are adjusted they are TIGHT with a little bend in them at the chain. I can't imagine using say 750# bars. That may be too springy. I think my problem is the long distance from the car axle to the trailer hitch. What do you think? 750#s? The hitch fellow is going to beef up my hitch.
The bending of your bars, is good.
That gives the rig some resiliency when hitting bumps, which is a good thing.
It's a "very bad" thing when the bars are hitting the A-frame.
The bars, under stress should be ball park, parallel to the A frame.
To correct the problem, in your case, is simply moving the ball mount so that it's tilted rearward.
