Some or all shocks listed are approved for road use; refer to the most recent certificate for current listings.

Multiple style options are available, including full show and covered finishes, with different spring and end-cap styles to suit your bike.

Made in the USA. 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 can alter the head angle and provide somewhat quicker steering; a slightly shorter shock can slow steering.

For bikes that are operated at or near the manufacturer's maximum load rating more than half the time, consider heavy-duty applications.

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.
