Some or all shocks listed are approved for road use; refer to the most recent certificate for current listing. All shocks are measured center-of-eyelet to center-of-eyelet. When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance. Before purchasing or attempting to install shocks that differ from the OEM length, confirm that wheel travel changes will not cause clearance issues such as swingarm/axle to exhaust contact or tire contact. Heavy duty applications are recommended for bikes operated at or near the manufacturer's maximum load rating over 50% of the time.
