Adjustable hood-stops are assembly units disposed on the front-end bolster of vehicles. These units are often designed to prevent any impact between the vehicle hood and the vehicle headlights. Further, the use of adjustable hood-stops may enable the transfer of forces upon closure of the vehicle hood or upon vehicle impact. Depending on the specific vehicle model, the front-end bolster may contain at least two adjustable and two non-adjustable hood stops. These adjustable hood-stop units include a retaining portion, that may be integrated or detachable, on the body of the front-end bolster that receives a threaded bumper stop piece.
