Keep in mind when we worked on these shocks and their design, it was designed around the Duff suspension components, spring rates etc. That being said I would expect similar improvements when coupled with other makes of springs like Wild Horse etc. but I would not expect the ride too be the same in comparison. These are engineered specifically for the bronco with improvements, inclusions etc. of things we liked from other tested brands as well as things we didn't like. So when installed on a bronco with a stiffer spring rate or less stages in the spring I would expect the ride to be a little more harsh based not he spring rates its coupled with. The springs are responsible for compression, the shocks are the rebound control.
