After extensive testing and the development of the Monsterjax, the R&D department at Bowjax has come up with the new RiserJax.  Riserjax come with two Monsterjax dampeners that are attached by a machined set screw through the holes in the riser.

RiserJax ll Dampeners have a base of 1" in diameter, fit up to 3/4" wide riser holes 

Riserjax will calm that previously untamed bow. If you've got a bow with some vibration in the riser, throw on some RiserJax and you'll notice the difference.
