The 2019+ Ram 3500 platform features a lowered rear stance compared to previous generations, creating a factory rake. This kit corrects that stance while delivering noticeable improvements in ride comfort, especially when loaded or traversing rough terrain. The progressive spring design ensures your truck maintains excellent working capacity while providing a much smoother, more controlled ride than the stock overload configuration.
