• Five-position cam-style spring preload adjuster lets you dial in your ride quickly.
• Simple, durable design provides a cost-effective suspension improvement.
• Multiple style options available, including full show-chrome or black covers, and chrome or black springs and end caps.
• 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.

Note: 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 can alter head angle and produce somewhat quicker steering; a slightly shorter shock can slow steering. Heavy duty applications are recommended for bikes operated near the manufacturer's maximum load rating more than half the time.

Before purchasing or attempting to install shocks that differ from OEM length, confirm that wheel travel can be altered without causing clearance issues such as swingarm/axle to exhaust contact, chain/belt guard interference, or tire contact.
