Important to know

Heavy-duty applications are recommended for bikes operated near the manufacturer's maximum load rating over 50% of the time. Before installing shocks with a different length than OEM, ensure adequate wheel travel to prevent clearance issues, such as swingarm/axle to exhaust contact or chain/belt guard or tire contact. When installing shocks on '86-'15 XL models, modifying or spacing the chain/belt guard might be necessary.
