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 Dampeners have a 1-1/2" base to fit cut out holes up to 1-1/4" wide.  You get one set to screw into the upper riser, and one set to screw into the lower part of the riser. 

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.
