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 provide somewhat quicker steering; a shock slightly shorter than stock can alter head angle and provide somewhat slower 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 different than the 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. Made in the USA. 🔧
