We noticed that most leaf spring naysayers gained their voice during the advent of spring-over suspensions using stock Wrangler spring packs-a common modification starting 10-15 years ago. The super-soft YJ spring packs weren't the best choice for a spring-over application and they helped give leaf springs a bad rap. Draw a line between the tire's contact patch to the center of the axle tube and that's the rotational fulcrum. Mounting the springs below the axle centerline reduces the leverage on the fulcrum and resists spring wrap, but mounting it above the fulcrum increases the leverage greatly. Even with traction bars, spring wrap and traction bar binding became such an issue that most turned to link-type suspensions as a cure-all.
