PROGRESSIVE SUSPENSION 412 Series Shocks — 330 mm (13") rear, Black, Chrome – 04-22 Sportster

The 412 Series shocks are designed specifically for Harley models and provide a simple, durable upgrade to your motorcycle's suspension. 🔧 Made in the USA.

Key benefits include:

• Five-position cam-style spring preload adjuster for quick, tool-free tuning.
• Durable design that offers a cost-effective improvement to suspension performance.
• Shocks are measured center-of-eyelet to center-of-eyelet for consistent fitment.
• Heavy duty applications are available for bikes operated near maximum load ratings.

Installation notes: when installing shocks on '86-'15 XL models it may be necessary to modify or space the chain or belt guard for proper clearance. A shock slightly longer or shorter than stock can alter head angle and steering feel. Before purchasing or attempting to install shocks different than OEM length, confirm wheel travel and clearance to avoid swingarm, axle, exhaust, chain/belt guard, or tire contact. 👍
