LimbSaver TwistLox Split Limb Crossbow Vibration Dampeners kit helps keep you in stealth mode even after the shot. Noise, or lack of it, is a critical part of crossbow hunting strategy, especially when a second shot opportunity presents itself. Often, additional noise results from vibration from the limbs, stock and string. For crossbow shooters, suppressing vibration and noise during the shot can be challenging. LimbSaver solves this common problem with an innovative dampener design. LimbSaver TwistLox Split Limb Crossbow Vibration Dampeners kit installs easier than any suppression system ever designed. Simply slide, twist and lock them into your crossbow's parallel limbs to finally put an end to noisy shooting and vibration. Includes 4 dampeners per pack. Weight: .5 oz. each. Made in USA.
