Add to the end of most modern day stabilizers, side bars, or v-bars with to reduce vibration in all axes…X, Y, and Z. Adjust stiffness from Ultra Soft for 1 to 5 oz weights, to Ultra Hard for up to 30 oz weights in seconds, by tightening or loosening the Kryptós to achieve the best vibration dampening results for any setup. Aerodynamic grooves have been tested to reduce wind resistance over dampers with bulging ball shapes The Kryptós was designed strong at the Ultra Hard setting to reduce the sag at the tip of your stabilizer when significant weights are added.
