  • Allows the shocks to sense the frequency of a bump and automatically adjust damping for superior ride quality
  • Deflective disc valving
  • You no longer need special tools to adjust, simply adjust the spring pre-load by hand
  • High-pressure gas charged with a progressive rate spring creates a consistent performance
  • Sold in pairs
  • Made in the U.S.A.


NOTE: A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering.

NOTE: A shock which is slightly shorter than stock may slightly alter the head angle and provide somewhat slower steering.

NOTE: Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time.
