Important to know

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. 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. Refer to the most recent certificate for current listing regarding road use approval.
