Reese, which is a top load equalizing hitch brand, uses the tapered bar.

That design allows flexing of the bars.

The side dimension stays the same, but the vertial direction changes from 1 inch at the trunnion to about 1/2 inch at the sway control cam. Those dimensions are for a 600 pound full sway control Reese hitch.

Any rating over that will punish your trailer.

I believe that tapered bars are somewhat more flexible than constant section ones, and also are a bit lighter in weight to handle. I don't think they make a big difference one way or the other. I towed with tapered bar Reese hitch bars for many years and it was a good system.

A tapered bar will most likely allow more up and down movement which may not be great when you hit a woop or are on concrete slab interstate. It will be easier on the trailer. You can always slow down or get some better shocks. I think I am using 750lb tapered bars.

If you test a 600 pound rated bar, which is actually 300 pounds since you use the overall complete rating. that is square and the tapered, you will find a huge difference in the bending.

We did a study with differ rated bars and manufacturers to prove that point.

The results of that test is on our website.

That article is labeled, "The Hitch Torsion Bar Story."

They do make a difference.

Try it.

We researched it.

From an engineering point of view, tapered bars give more uniform stress within the bar. Stress is caused by the bending moment at any particular cross section along the bar. Therefore; highest at the trunion and lowest where the cam or chain attach. Therefore you can use less steel in the bars without over stressing them, They, therefore, are lighter to handle. Good engineering, but more expensive to make that round or uniform thickness bars.
