Planning to haul some original trim, gauges, and small NOS Chevy parts back from an upcoming swap meet and looking at small 5x6 enclosed options.

Main issue is getting a smooth ride out of a lightweight single axle on rough highways. I was looking at this torsion setup / <a class="ng-star-inserted" href=" removed link " target="_blank" rel="noopener" data-hveid="0" data-ved="0CAAQ_4QMahgKEwjFwKPHy46WAxUAAAAAHQAAAAAQ7wk"> removed link   to see if choosing that over leaf springs actually smooths things out, or if single axles are just inherently rough regardless of suspension type.

Do torsion axles actually make a noticeable difference on light 5x6s, or is it not worth the upgrade over standard springs?
