PROGRESSIVE SUSPENSION 412 Series Shocks — 318 mm (12.50"), rear, black – 82-94 FXR, 84-85 Big Twin, 84 Police, 77-03 Sportster

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

A five-position cam-style spring preload adjuster lets you easily dial in your ride. Multiple style options are available, including full show-chrome or black covers, and 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.

All shocks are measured center-of-eyelet to center-of-eyelet. When installing shocks on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard to allow proper clearance. A shock slightly longer than stock may alter the head angle and quicken steering; a shock slightly shorter than stock may slow steering. Heavy duty applications are recommended for bikes operated near the manufacturer's maximum load rating over 50% of the time. Before purchasing or attempting to install shocks that differ from OEM length, confirm wheel travel and clearances to avoid contact with swingarm, axle, exhaust, chain/belt guard, or tire. Made in the USA. 🇺🇸
