Torsion axle v spring axle
Ok lets try this. How much does a spring axle go up and down?? How much does a torsion axle go up and down?? Does a spring have more travle or the torsion have more? Better ...

One advantage of the torsion axle with swing arm is lack of "bump steer". When the lead wheel on one side of the trailer encounters a bump that the other side's lead wheel doesn't run over on irregular road surface, the wheel in it's "Up" travel is steered out. This is because the leaf spring, as it's arch is straightened from the bump, effectively gets longer from pivot point and axle attachment point. This may cause the trailer to steer slightly to one side or another and it's compounded when the second axle does the opposite as it encounters the same bump. How much this may contribute to overall trailer "sway" is dependent on other factors as well but it's part of the overall issue.
Torsion axles with swing arms hold the wheel in the same direction as it goes through it's entire "bump travel".
To me the torsion spring equipped trailer tracks far better than leaf springs with equalizers.
