I'll be the first to admit my 2" lift is all for show so don't bag on me about talking sway bars in a lifted forum. I have quick disconnects on the bars for my trail ride but that is another post.
Just wanted to chime in and say I installed the Hellwig rear sway kit on my Astro. Was on sale from suspensionconnection.com. Install was quick, easy and made a big diff in street driving. I expect it to help a bit when towing the travel trailer too.
It's been a long time since I had time to visit the board, hope all have been well!
