maybe a Cal-tracks style traction bar, or a ladder bar really. if you are getting too much axle wrap, going stiffer on the spring to correct that will require going past ideal into too stiff a ride. and too soft a shock can also allow hop even with a good anti-wrap bar.
i agree with trying a non air shock, something like the RS9000 or a QA1 that's adjustable. the air shock might not be the right thing.
"springs just support the weight", but having something the increase in load capacity as it compresses can help the suspension tuning too. maybe try one of those ad-on overload leaves that bolt on top of the pack. would allow you an adjustable pre-load too. when tuning dual-rate coil overs, i like to set the dual-rate stop JUST off the slider at ride height. this means any droop is at the soft spring rate, but any compression is under a much higher rate. cornering this acts like a sway bar with the compression side having a stiffer spring than the unloaded side. if your suspension has a little squat under launch, it can also help you be landing in the stiffer rate to control motion.

something like the link ... as you tighten the outer u-bolts, you'd change the preload and when it begins to act.
