PROGRESSIVE SUSPENSION 412 Series Shocks — 305 mm (12.00") extended length, rear mounting – 91-17 Dyna, 01-02, 07-10 CVO

Designed specifically for Harley models, the 412 Series Shocks deliver durable, cost-effective suspension improvements for a smoother ride. 🏍️

The five-position cam-style spring load preload adjuster lets you easily dial in sag and handling to suit your load and riding style.

Available in multiple styles—full show-chrome or black covers and either chrome or black springs and end caps—so you can match the look of your bike.

All shocks are measured center-of-eyelet to center-of-eyelet; before changing from OEM length, confirm wheel travel and clearance to avoid swingarm, axle, exhaust, chain/belt guard, or tire contact issues.

Made in the USA; some or all listed shocks may be road-legal—refer to the most recent certificate. Heavy duty applications are recommended when operating near the manufacturer's maximum load rating over 50% of the time.
