412 Series shocks are designed specifically for Harley models and deliver a simple, durable, cost-effective improvement to suspension performance. 🏍️

The five-position cam-style spring preload adjuster makes it easy to dial in your ride.

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

• 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.

When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain or belt guard to allow proper clearance.

A shock slightly longer than stock can alter the head angle subtly and provide somewhat quicker steering; a slightly shorter shock can result in somewhat slower steering.

For heavy duty applications, choose shocks rated for frequent operation near the manufacturer's maximum load rating.

Before purchasing or attempting to install shocks that differ from OEM length, confirm that wheel travel and clearances (swingarm/axle to exhaust, chain/belt guard, and tire) will not be compromised.
