Important to know

When installing shocks on '86-'15 XL models, modification or spacing of the chain/belt guard may be necessary for proper clearance. Confirm that 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, before purchasing shocks of a different length than the OEM specifications.
