Hi Steve,
You're saying your fully loaded tongue weight is higher than the spring bar capacity? I would correct that immediately with the 1,200lb capacity spring bars # FA92-02-1299 you referenced, but I don't think that will totally solve your issue. Typically if it's bouncing the spring bars are too high capacity for the tongue weight. The best course of action is to stop the road shock before it travels past your suspension. Adding in some SumoSprings to the trailer can help cushion the blows from the road and help support your leaf spring suspension.
To pick out the right kit for your trailer you'll want to check if the leaf springs sit above or below your axles and the weight capacity of the axle. There should be an axle tag stick on the axle tube that lists the capacity. Based on the tongue weight I'm guessing you probably have 5,200lb axles, but it would still be good to double check.
