What are the differences between a Round Bar and Trunnion Bar in a Weight Distribution Hitch System?

Trunnion Bar

There are two types of spring bars, round and trunnion. The round style bars slide up into the head and are held in place with clips. The trunnion style bars slide into the head from the side or back.

Like Equalizer Head's, spring bars vary by weight distribution systems - look at your systems parts break down for part numbers.

He said essentially: 'Trunnion bars are easier to install and have less ground clearance issues'. Seems like a no-brainer to me.

Hi John - here's some additional info to help clarify further: The main difference between the two systems is basically the attachment point of the bars. The trunnion bars are a little easier to install than the round bars that require a clip to hold them into the head. The head on trunnion bar units does not come down and the bars do not stick out of the bottom, so there are less ground clearance issues. This can be ideal for low sitting trailers such as horse trailers. Round bars are easier to adjust for the angle of the ball mount to get the system in the correct position for towing and weight distribution. Neither setup is necessarily better than the other, it's just two different styles based on your own preferences. If there is anything else we can do to help please let us know - info@hitchweb.com or 1-800-300-4067 Thanks!
