The overdrive servos are a power armor leg mod in Fallout 4.
Effects[]
When installed on a power armor leg piece, the player character gains an increased sprint speed at the cost of increased AP drain while sprinting. The benefit of sprint speed and consequence of AP cost can be stacked twice by equipping the mod on both legs or they can be roughly balanced by equipping this mod on one leg and equipping the optimized servos (reduces AP cost for sprinting) on the other.
The 25% AP cost increase is applied after the sprinting cost is decreased according to the player character's Endurance (see that page for more details). For example, having 21 Endurance equates to spending 0 AP on sprinting with or without the effect of the mod. In addition, the armor's fusion core expenditure will be exactly the same as when jogging instead of sprinting.
Crafting[]
In order to craft the overdrive servos, a power armor frame with the desired leg piece(s) attached must be installed at a power armor station.
