Important to know

Some shocks listed are approved for road use; refer to the most recent certificate for the current listing. 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 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 from 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.
