Upgrade your ride with the 412 Series Shocks — a simple, durable option designed specifically for Harley models. These shocks offer a cost-effective improvement to suspension performance and provide reliable, consistent damping for a wide range of riding conditions. 🏍️

Key features:

• Five position cam-style spring preload adjuster lets you dial in your ride quickly and easily.
• Some or all shocks listed are approved for road use; refer to the most recent certificate for current listing.
• Multiple style options are available, including full show-chrome or black covers, and chrome or black springs and end caps.
• 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 quicken steering; a slightly shorter shock can slow steering. For heavy duty applications, choose shocks 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 interference, or tire contact.
