It looks like our OE rear is 5/8”and I see options from Addco and Helwig at 3/4” has anyone tried either of these?

How is that a better option?
It’s the same dia bar with likely longer arms so a lower rate vs a stock location mounted bar.
Plus it requires additional maods

My understanding is that the rear AR is stiffer than stock.

I’ts def a larger diameter, I don’t know the arm length to do a rate calculation. If it’s matching the front AR, it’s around 75ft/lb
I do know it’s not an option without a BL and welding link tabs on that complicate future outboarding
 
I have the Helwig I got for free and installed only because my end links were worn. It definitely firmed it way up in the rear in the middle hole. So much so I moved it to it's loosest setting. Middle was fun and easy to rip a donut with, but it got to tail happy around sweepers. Since my Jeep isn't a Miata, I prefer a slight understeer bias.

Everybody should remember that bigger sway bars ≠ "better" handling. They are a way to tune your suspension just like anything else. Too firm of a sway bar at either end is going to cause some dramatic under/over steer.

The Helwig has 3 positions?
Whats the length of the arm to each hole?

Assuming the center hole is the same as OE and the centers are 1” appart. That means +/- 1” from oe arm length. It looks like ~50# difference for each hole.

Good to keep in mind. I also have mine in the loosest setting. I was wanting to have a roof top tent down the line so that was a contributing factor in me getting it.
