Steambow AR-Series-Side Panels with String Dampeners Black. The string dampers lead to a clean release of the arrow from the string and thus slightly increase precision. At the same time however a lot of residual energy is absorbed from the system making the limb more forgiving towards arrows that are too light. String dampers are recommended from a draw weight of 90 lbs. ATTENTION: Nevertheless pay attention to the minimum arrow weight and avoid dry shots. When fitting make sure that the screws on the side plates are not tightened more than hand-tight and never overtighten them.
