PROGRESSIVE SUSPENSION 412 Series Shocks — 342.9 mm (13.5"), Black – 96-17 Dyna, 01-02, 07-10 CVO

The 412 Series Shocks are designed specifically for Harley models and provide a simple, durable, cost-effective improvement to your motorcycle's suspension performance.

A five-position cam-style spring preload adjuster lets you quickly dial in ride feel and support for a variety of loads and riding styles.

Multiple style options are available to suit different aesthetics and installations.

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

All shocks are measured center-of-eyelet to center-of-eyelet. Before purchasing or attempting to install shocks that differ from OEM length, confirm wheel travel and clearance to avoid swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.

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, while a slightly shorter shock can produce somewhat slower steering. For bikes operated near the manufacturer's maximum load rating more than half the time, consider heavy-load applications and appropriate setup.
