Bowjax Ultrajax II Bow String  Dampener & Silencer

The Ultrajax II bow string silencer has been our most popular model with bow companies and consumers for the past two years. It’s been a top seller because of its effectiveness. Ultrajax II slip over the bow string to effectively dampen the noise, vibration, and oscillation that occurs after the shot. They require a bow press for installation. For compound bow users that are looking for even more dampening ability, attach a Ultrajax II to your cable. These weigh 19 grains each.

  1. Rated 5 out of 5

    This is my first go with these, but I found them easy to install and they look good. I put them on my cables so I don’t suspect any issues with them tearing off. They seem to do the job just fine.

  2. Rated 5 out of 5

    Like that they are compact unlike cat whiskers. Also like that they go over the string rather than through it.

  3. Rated 4 out of 5

    they are fairly easy to get on the string, but they make my bow quiet. never has it been this quiet!

  4. Rated 5 out of 5

    these are smaller than the factory ones that were on my string but work better

  5. Rated 5 out of 5

    The best string silencers on the market in my opinion.

    I’ve tried out cat whiskers and beaver balls and both of those silencers act like giant flu flu’s on the string and cause a significant decrease in arrow speed on a traditional bow. My bow was also still loud while using those silencers.

    They are also a pain to get on the bow and I don’t like the look of giant pieces of fur on my string.

    After tuning my recurve recently and sliding these on the string my bow is very very quiet without having to use heavy arrows.

    I also like the fact they slide on the string. I don’t have to worry about them coming off the string while hunting or stumping and with a little bit of string wax under them I’d imagine they will last at least 2-3 months shooting a lot each day.

    I don’t notice much of a difference in arrow speed with these installed, if I had to guess there’s maybe a loss of 2-4 fps on a stickbow with all 4 installed, plus they are more aerodynamic than the other silencers and look cooler while also making for a quieter bow all while being naturally water proof.
