PROGRESSIVE SUSPENSION 412 Series Shocks — 305 mm (12") extended length, Rear, Black/Chrome – 91-17 Dyna, 01-02, 07-10 CVO

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

• 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 for precise fitment.
• Multiple style and finish options are available to complement your bike.
• Some or all shocks listed are approved for road use; refer to the most recent certificate for current listing.

When installing 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 head angle for quicker steering; a slightly shorter shock can slow steering.

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 contact with exhaust, chain/belt guard, or tire. Made in the USA 🇺🇸 📏
