When installed on power armor, the optimized servos reduce the AP cost when sprinting. The ability to run while overencumbured obtained through the Strong Back perk counts as sprinting, and the AP cost is mitigated by this mod.
In order to craft the optimized servos, a power armor frame with the desired leg piece(s) attached must be present at a power armor station.
