I believe there is a design that has a tube bolted to the axle or the spring in front and behind the axle that slides inside another tube that is fixed to the frame - this allows the axle to move back and forth but keeps it vertical and resists the spring wind up.
For vehicles with a large suspension movement you really need coil springs and multi-link location of a live axle or independent suspension.
One of my biggest beefs with the after-market tuning accessory sellers is that they sell stuff that either doesn't do the job they claim or can actually make the situation worse.
If a vehicle manufacturer fits traction bars, I would expect the design and mounting of the bars to minimise the discrepancy in movement.
