Reduce Vibration While Securely Mounting Hand Guards. Threaded Anti-Vibration Inserts absorb vibration while securing your hand guard. The result is a solid hand guard anchor that minimizes vibration. An incredibly effective component for any serious racer or casual rider, our inserts absorb the vibration transferred from the bars to your hand yielding less fatigue and arm pump. Constructed out of brass, the Threaded Inserts require you to tap the end of your handlebar with the included tap. Once the bar is tapped the Threaded Inserts can be installed and are ready for your hand guards to mount to. The Threaded Anti-Vibration Inserts come with two inserts, one tap, two o-rings and two 35mm 8x1.25 bolts to secure your guards to the insert. **Not compatible with Renthal Twinwalls
