Equalizer hitch - how to tell which one I have

IMO one significant drawback to the Equal-i-zer system is that each spring bar will only fit the head designed for that weight rating ... change spring bars and you gotta change the head, meaning you might as well sell the entire unit and buy another with the correct weight rating. In contrast, if you own a Blue Ox Sway Pro and change to a heavier or lighter trailer all you need to do is replace the spring bars, everything else remains the same.

Agree! If I was the OP I would certainly look at other brands like Husky, Blue Ox, Reese, etc.

Equal-i-zer Spring Arms are rated @ 400, 600, 1000, 1200, and 1400 lbs ... heavier bars are thicker. All Equal-i-zer hitches are labeled with the model number so unless it's been removed or painted over determining it's weight rating is as simple as looking at the label.

I am glad you asked this. I was wondering the same thing. I am moving to a larger travel trailer but I am not sure which Equal-i-zer hitch I have.

My Equal-i-zer brand is a 1,000 lbs version as evidenced by the label on the bars which read 90-00-1000 and 1,000 max tongue weight and 10,000 max trailer weight.

The hitch has "C1" molded on the head near one of the bar pivot bolt heads.

I bought this new with my current trailer 3 years ago so the labels are still legible. I don't have another to compare with. Maybe a local dealer has a couple that would give you a clue. My bars are 1-3/8" square if that helps.
Their parts manual does not give physical dimensions but perhaps the bar sizes are measurably different.

Maybe Equal-i-zer would give you some specs. That would be handy if buying used and the labels are gone.
