  • All shocks are measured center-of-eyelet to center-of-eyelet.
  • When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance.
  • A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering.
  • A shock which is slightly shorter than stock may alter the head angle slightly and provide somewhat slower steering.
  • Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time.
  • Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.
