I found the thread named "2019 RAM 1500 hellwig swaybar" started May 29, 2018. Just type it in search bar. It has 3 pages of discussion about adding the bar. I remember everyone there seemed to feel it was worth the money. Some that tow fairly heavy trailers/load in box felt it gave rig better planted feeling. As to your question about me wanting to try stiffest setting, why not? If some is good, maybe more is better? Remember dating????

lol If it seems like I am getting excessive oversteer on corners, or feels odd at all, I will adjust it back to middle setting. I am sure it is safe to use the most aggressive setting or it wouldn't be an option by engineers if dangerous. I like the flat cornering like a go-cart feeling but I also don't plan on scrubbing tread off my new Goodyear Wrangler Duratrac tires by trying to play Porsche in the curves. Could swap ends and crash a $62k truck that is definitely not intended to race through corners. I did not notice any negative impressions since adding it as it won't hurt ride on straightaway and helps cornering with less body roll. Now if you go severe off road and want rear axle to be able to articulate with one wheel stuffed in fender to top of suspension and other wheel hanging at bottom of travel like rock crawling, then this bar would probably restrict severe angles of back axle. I don't go beyond playing in snow and too expensive of rig to trash it.
