BowJax SlimJax Solid Limb Dampener Red (2 Pack) The advent of newer slim limb compound bows and recurve bows has brought out a demand that Bowjax is glad to answer. Building on the success of the original 4 arm limb dampener, the R&D department at Bowjax is proud to introduce the Bowjax Slimjax solid limb dampener. Our research has shown that a limb dampener that actually contacts the limb is more effective at knocking out noise and vibration than a dampener that has no contact with the limb. For this reason, Bowjax Slimjax are the most effective limb dampeners that you can get for your thin limb compound bow or traditional archery equipment.
