Enhance your Harley's rear suspension with the 412 Series Shocks — designed specifically for Harley models and built for long-lasting performance. 🏍️

The 412's simple, durable design offers a cost-effective improvement to ride quality, and a five-position cam-style spring-load preload adjuster lets you easily dial in your ride.

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

Multiple style options are available, including full show-chrome or black covers, or chrome or black springs and end caps.

All shocks are measured center-of-eyelet to center-of-eyelet, and they are made in the USA.

Installation notes: 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 may alter the head angle and provide somewhat quicker steering; a slightly shorter shock may provide somewhat slower steering.

Heavy duty applications are recommended for bikes that are 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.

• Standard for Harley-Davidson FLT/FLHT/FLHR/FLTR '84-'05.
• Heavy duty for Harley-Davidson FXR '87-'94.
• Heavy duty for Harley-Davidson XL '86-'03.
