PROGRESSIVE SUSPENSION 412 Series Shocks — Heavy Duty, 279.40 mm (11.00") extended length, Black – 82-94 FXR, 77-03 Sportster

The 412 Series Shocks are designed specifically for Harley models and provide a simple, durable upgrade that improves suspension performance. 🔧🏍️

Featuring a five-position cam-style spring preload adjuster, the 412 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.

Multiple style options are available, including full show-chrome or black covers and chrome or black springs and end caps. All shocks are measured center-of-eyelet to center-of-eyelet and are made in the USA.

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 than stock can quicken steering by altering head angle; a shorter shock can slow steering. For heavy duty applications, choose models recommended for sustained max-load use. Before purchasing shocks different than OEM length, confirm wheel travel and clearances to avoid contact with exhaust, chain/belt guard, or tire.
