"Without the ACOS Pro bump stops, we might be tempted to use stiffer coil springs to avoid bottoming the suspension. But with the bump stops in place, our JK has the ability to soak up the bumps affording a softer, more compliant set of springs. We think the ACOS Pro system is a perfect combo if you are looking for a stock ride and mild lift height. Under full compression, 35-inch tires will clear perfectly on every corner."
