• 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.
• A shock slightly longer than stock may alter the head angle and provide somewhat quicker steering; a slightly shorter shock may slow steering.
• Heavy duty applications are recommended for bikes operated at or near the manufacturer's maximum load rating over 50% of the time.
• Before purchasing or attempting to install shocks that differ from OEM length, confirm wheel travel and clearance to exhaust, chain/belt guard, or tire contact.
