The new LimbSaver® ULTRA is a dramatic improvement over all previous LimbSaver® designs, and outperforms all of the competition…guaranteed. The new ULTRA reduces limb shock and vibration by up to 80%, and reduces noise by up to 20db. Engineered to incorporate a new specialized geometric design for greater 360° movement, the ULTRA utilizes our patented LimbSaver® technology, and our proprietary NAVCOM™ material.

When the crossbow shot of a lifetime is at hand, you need to make it count. You will be glad you relied on the new LimbSaver® Crossbow System. After years of research and requests for sound and vibration damping products for crossbows, Sims Vibration Laboratory has revolutionized the crossbow industry with the introduction of the first-of-its-kind crossbow-silencing system. Designed to install on virtually any crossbow, this new three-part damping system is guaranteed to reduce sound and vibration to a level never experienced before.

Now available separately, these remarkable String Silencers reduce string vibrations and noise for a quieter, smoother shot. While designed primarily for Crossbows, these units also work perfectly on compounds, longbows and recurve's.

Designed for absolute performance, the String Leech® delivers maximum reduction of string noise with minimal to no speed loss. Incorporating a string wedge to resist string cutting, the String Leech® is made with our proprietary NAVCOM™ (Noise And Vibration Control Material). Developed for hunting, it is the ultimate string silencer. A revolutionary product that works! Now standard on many new PSE® and Hoyt® bows. See your local dealer for leech replacement.
