Help the sway

I think the CHF is a 50 - 50 chance of improvement on handling and sway. Sumo springs are an improvement, but does not solve the issue. Our F53, 24K chassis came with Sumo springs and drove like a bread truck with sway, porpoising and rough ride. Depending on how much you want to spend, you can pretty much solve the problem. Items that work: replace front anti-sway bar with loadmaster 1 3/4" sway bar, rear, forward facing anti-sway bar(s), in addition to existing bar, Koni FSD shocks, and rear trac bar. You can take a piecemeal approach or go full bore on upgrades. Also consider 4 corner weight and adjusting air pressure accordingly. If I was gong to take a piecemeal approach to the upgrades, I would do the following: front ant-sway bar, rear sway bar and rear trac bar - maybe $3k - $3.5 K if you have it installed by a shop.
