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 altering wheel travel does not cause clearance issues before purchasing shocks of a different length than OEM. Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time.
