A result of extensive development & testing, the new TwistLox limb dampeners noticeably dampen noise and vibration when shooting your compound bow. Installation is easier than ever! Simply slide in, twist, and lock up for a snug and secure fit. They can be installed in two orientations for wide or narrow-spaced limb gaps, and can be positioned to the shooter’s preference, using two or more TwistLox dampeners per limb. Mix, match, and color coordinate.
