Choose Your Perfect Feel - We have 2 tennis shock absorber types. Each offers you a choice of different sizes, shapes and densities. This lets you find the perfect balance of dampening, feel and stiffness that suits your playing style. Never Lose Your Tennis Racket Dampener Again - The ADV tennis dampener has a unique internal grooved structure that locks on the racket. Unlike standard tennis vibration dampeners, ours stays connected to both cross & main strings, stopping it from popping off. Built From Long Lasting Engineered Poly-Silicone - These tennis shock absorbers are built with a proprietary poly-silicone blend developed by our engineers. They can withstand heavy & frequent contact. They’re meticulously made with dense composite materials for extra durability. Reduce Impact & Injuries - Minimize harmful shock on your wrist & elbows when using our tennis racket shock absorber. It works well to lessen vibrations that may hurt your elbow or cause strain.
