Tennstrike’s Silicone Vibration Dampeners are engineered to give you a smoother, quieter feel from your racket without changing your game. Made from high-quality silicone, these little shock absorbers sit between the center mains and absorb a portion of the string vibration transmitted at impact — helping reduce sting and improve comfort during long practice sessions or matches. Many players also prefer the muted impact sound they provide, which removes distracting string “buzz” and gives a more satisfying, muted pop at contact. Built to last, our silicone formula keeps its flexibility and performance across temperatures and repeated play, resisting cracking and deformation common with cheaper materials. The compact button-style design installs in seconds and stays secure during serves, volleys and powerful groundstrokes. Tennstrike dampeners are an easy, low-cost upgrade for players looking to improve feel and reduce shock without altering string pattern or tension.
