Ladder bars..??..

I think the bars themselves would be ok without doubling them, it's just the connection between the bar and that spring pad style axle bracket that's suspect. Proper gusseting could fix the problem, but if I was building the bars from scratch I would make the bar's side plates go all the way up to the axle tube and eliminate the small spring pad bracket.

I was thinking possibly doubling the spring pad bracket going on the bottom and on the back side and using a solid long piece of stock down the back? Another crude drawing LOL... I like the way the spring pads are radiused the same as the axle...
and I'm assuming that the front shackles are the complete ticket for not letting anything behind?..
