PROGRESSIVE SUSPENSION 412 Series Shocks — 279.4 mm (11.00"), Rear, Chrome – 91-17 Dyna, 01-02 CVO

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

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 current listing.

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 slightly longer shock may alter head angle and provide somewhat quicker steering, while a slightly shorter shock may result in somewhat slower steering.

Heavy duty applications are 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 or chain/belt guard or tire contact.
