PROGRESSIVE SUSPENSION 412 Series Shocks — 279.40 mm (11.00 in) extended length, black – 91-17 Dyna, 01-02 CVO

The 412 Series Shocks are a simple, durable upgrade designed specifically for Harley models and made in the USA.

A five position cam style spring preload adjuster lets you easily dial in your ride. All shocks are measured center-of-eyelet to center-of-eyelet.

• Multiple style options: full show-chrome or black covers; chrome or black springs and end caps.
• Some or all shocks listed are approved for road use; refer to the most recent certificate for current listing.
• Heavy duty applications are recommended for bikes operated at or near the manufacturer's maximum load rating over 50% of the time.

When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance. Before purchasing or installing 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. A shock slightly longer than stock may alter head angle and quicken steering; a slightly shorter shock may slow steering.
