Flipping the axle from underslung to overslung will raise the trailer’s center of gravity, potentially making it more sensitive to cross winds. If your trailer travels securely on the road at all times, flipping the axles will not be a cause for concern.
How much lift does a spring over give you?

What kind of Springs does a Jeep Wrangler have?
Older Wranglers (YJs) have leaf springs, while newer models have coil springs. Both are designed to absorb vertical impacts. When a vehicle goes over a bump or a hole, there is a vertical impact. The force of the impact is absorbed and distributed within the spring. The shock, or dampener, helps tame the energy absorption.
