Size of 600lb Reese Trunnion bars?

[glacierrunne]

I am looking for a pair of 550-600 lb Reese Trunnion bars. Is the diameter 1 inch? What is the overall length?. I have found a pair with no ratings and want to make sure they are the right ones before I buy them. The pair forsale is straight and does not have the curve where the chains are connected--- does that matter? Thanks, Don in Idaho

The older bars did not have the curve, They used a bolt on piece if it was to be used with the dual cam system. Otherwise the chain bolted to the bar.

My memory says that one inch is right for the 500 lb bars but perhaps someone else will confirm it.
The length of the bar from where it leaves the trunnion to the end should be about 25 inches

If the bars are straight, 1" at the top of the bar, measured at the trunnion, is 450 pounds/.

1 1/8 inch is 650 and 1 1/4 inch is 900 pounds.

Adding the dual cam sway control, adds 100 pounds to each of those ratings.

Andy, Rick, thanks for the information. I bought the bars, and they were marked 750 lbs. I've been using 800 lbs so I am going to try and trade one of my sets for lighter ones! Thanks again, Don
