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. 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.
