Take the vibration and noise out of your limbs by up to 80% by installing a pair of Super Quad's. The innovative design is both extremely efficient and effective. And to make them even more versatile, the Super Quad can be used in both 1/2-3/4 and 3/4 to 1-1/8 split limb spacings. Just rotate the dampener to the side with the correct spacing and push the dampener between the limbs until you feel it sit in the grooves that hold it in place. No brackets or hardware are required for this universal application. Per 2. Color: Camo. Type: Silencers.
