This Crossbow Kit really takes down the noise level. The research and design team at Bowjax set to work on dampeners that can work to quiet even the most powerful crossbows.
Instructions: The limb dampeners should be placed midway distance between the cams and barrel. The limb dampeners are universally sized to fit gaps between 3/8" up to 1 1/8" wide. These install easily with provided screws. You should place the arms of the Limb Dampeners parallel to the limbs and face them on the inside of the limbs.
Instructions for Retention Spring Dampeners: You'll want to place these approximately half-way down the spring, leaving fletching clearance.
Instructions for the Stirrup Dampeners: These install easy without a bow press if you have a removable style stirrup (with a screw in place). You simply unscrew the stirrup and place one on each side of the stirrup as shown. If you don't have a removable stirrup, Bowjax don't recommend using stirrup dampeners
