Question:
I have the fastway e2 weight distribution system with 8000 lb trunion spring bar. I think its over engineered for my setup. If I buy the 6000 lb trunion spring bar can I use the existing 800 trunion socket or do I need to purchase a 600 trunion socket. It looks like the 6000 lb bar would fit. Im assuming trunion I have is for the 8000 spring bar because it says 800 on the side on the trunion socket. Does that mean they make a 600 trunion?

Hi Jim; that does indicate it is for the 800/8,000 lb system. They do make a lower rated trunnion # FA92-02-0644 but you don't have to replace yours with the lower rated component. You can swap out your spring bars for the # FA92-02-0699.
Are you getting a rough, bouncy ride with the existing spring bars?

Yes rough and bouncy on poor highways. My only concern with lower spring bars is my tongue weight is 725lbs but by trailer dry weight is 5,200 lbs. So it seems I need the 800 lb spring bars?
