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 and are made in the USA.

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 that is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering, while a slightly shorter shock may slow steering response.

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 that wheel travel can be altered without causing clearance issues such as swingarm/axle to exhaust contact, chain/belt guard, or tire contact.
