"Active Off-Road Bumpstops provide off-road enthusiasts greater control over their vehicles' suspension travel. Using progressive-rate springs means that instead of a hard stop at the end of axle travel the axle energy will be absorbed when bottoming-out producing smooth, predictable, quiet axle engagement and disengagement.
