Designed specifically for Harley models, the 412 Series delivers a simple, durable design that provides a cost-effective improvement to your motorcycle's suspension performance. 🏍️

A five-position cam-style spring load preload adjuster lets you quickly and easily dial in your ride for comfort or control.

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-to-eyelet to center-to-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 head angle for quicker steering, while a slightly shorter shock can slow steering. Heavy duty applications are recommended for bikes operated near the manufacturer's maximum load rating over 50% of the time.

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