2" Bilstein struts come pre assembled with King Springs and HD strut top mounts.

Please be aware that all kits are dispatched at a height that is set from our experience to the advertised height in the product listing, we cannot be held accountable for variations on vehicles and or the variation of weights of accessories that would require further adjustments of heights once installed. Any height adjustment required to achieve the desired ride height is at the installers discretion and at no way our responsibility.
