Provided is a downhole tool, a well system, and a method. The downhole tool, in one aspect, includes a mandrel, a sliding element positioned radially about the mandrel, and a pressure intensifier positioned radially about the mandrel and coupled to the sliding element. In one aspect, the pressure intensifier includes a first piston having a first pressure receiving end with a larger piston surface area (A.sub.L1) and a first pressure output end with a smaller piston surface area (A.sub.S). In one aspect, the pressure intensifier includes a second piston coupled to the first piston, the second piston having a second pressure receiving end with a larger piston surface area (A.sub.L2). In one aspect, a fluid chamber is defined between the first pressure output end and the second pressure receiving end. In one aspect, the pressure intensifier is configured to move the sliding element with an applied force.
