Installation notes: 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 slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering; a slightly shorter shock may provide somewhat slower steering. For heavy duty applications—bikes operated at or near the manufacturer's maximum load rating over 50% of the time—choose appropriately rated units. Before purchasing or attempting to install shocks that differ from OEM length, confirm wheel travel and clearances to avoid swingarm/axle to exhaust contact, chain/belt guard interference, or tire contact.
