Important to know
When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard for proper clearance. A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering, while a shorter shock may result in somewhat slower steering. Heavy-duty applications are recommended for bikes operated near the manufacturer's maximum load rating over 50% of the time. Before purchasing shocks with a different length than OEM, ensure wheel travel can be altered without clearance issues.
