Note: All shocks are measured center of eyelet to center of eyelet.
Note: When installing shocks on 86-18 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance.
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 alter the head angle slightly 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.
Note: Before purchasing or attempting to install shocks that are different than the O.E.M. 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.
