Abstract
A preferred embodiment of the present invention includes a triple torsion axle system and kit with various features to help reduce or prevent damage that otherwise may occur with large loads. For example, each axle assembly includes larger diameter caps on the ends of each torsion bar to prevent the bar from pulling out of its outer tube during high side loads. In another example, the outer end of the torsion bar has a rounded surface that is fixed to a swing arm so as to better equalize the stress around the weld joint. Additionally, the triple torsion axle is configured such that when the vehicle is unloaded, the middle axle assembly supports more weight than the two adjacent axle assemblies. However, when the vehicle is loaded, all three axle assemblies provide similar support to the vehicle.
