Re: Is there anything that can be done to reduce fish-tail action?

im suggesting get your wheel alignment checked after several goes at mine i have reduced the effects you are describing, seems to me its pretty common with the jeep.
also i would try reducing tyre pressures not increasing!! i run 36psi anything more and it does skip/bounce. i have also heard the srt's suffer it also so i cant imagine a simple swaybar swap fixing it. it has more to do with vehicle design. theres lots o moving parts in this suspension so make sure all parts are 100% serviceable and not worn out.

It's a pain in the ass because the dealer is flat out denying the issue.

As a follow up for mine - my dash readout was showing all 4 tires as being over-inflated but "OK". I ran over to a local tire dealer and had them check the pressures. All 4 were over-inflated. Since they adjusted the pressure down, I haven't noticed the issue. I have put 1,500 miles on since having the pressure adjusted last Wednesday, too.

Re: Is there anything that can be done to reduce fish-tail action?

Have '13 GG Trailhawk with same issue - "squirming". I looked on line over past 2 days & made calls. No one makes aftermarket thicker sway bar (existing is 22mm) for 2011-2014. Higher tire pressure helps and I need to replace tires before winter and may not go with the GY Wrangler silent armor this time. As for SRT8 sway I thought they were same size, but if larger I'll consider replacing rear bar only. Two previous GCs did not have such a pronounced movement.

Re: Is there anything that can be done to reduce fish-tail action?

That sideways hop shouldn't be happening on a full cabin vehicle like an SUV, especially ones without full rear axles. That's purely the domain of pickups, especially small ones like the Ranger, S-10, Colorado, etc.

If your Jeep is doing it, something is wrong that should be fixed.

Higher tire pressure wouldnt be helping either would low profile tires.

Re: Is there anything that can be done to reduce fish-tail action?

The OP appears to have a Limited which comes with 18 inch tires which in itself enhance any lateral body roll because of the tire flex. So tires would have to essentially be over inflated to correct the behavior.

All cars especially those non-specialty cars sold for street use in US are mechanically set up to understeer. Understeer is safer and easier to control for the average driver. As such, the rear sway bars are thinner and lead to this kind of driving behavior. Getting a thicker rear sway bar will largely correct the problem. I experienced similar behavior on the SUBARU and the 20 mm diameter rear sway bar from the Japanese model cured it. Factory size for US market was 16 mm.

Over inflated tires will make it skip across corragations
