All shocks are measured center-of-eyelet to center-of-eyelet. When installing on '86-'15 XL models it may be necessary to modify or space the chain or belt guard for proper clearance.

A slightly longer or shorter shock may alter head angle and steering feel, and heavy-duty applications are recommended for bikes operated near their maximum load most of the time. Before changing OEM length, confirm wheel travel to avoid clearance issues; refer to the most recent certificate for current road-approval listings.
