PROGRESSIVE SUSPENSION 412 Series Shocks — 330 mm (13") length, rear, Chrome – 71-86 Big Twin, 80-90, 95 Touring, 82-85 FXR, 84 Police

The 412 Series Shocks are designed specifically for Harley models and deliver a simple, durable improvement to your motorcycle's suspension performance. A five-position cam-style spring preload adjuster lets you easily dial in your ride for better comfort and control. 🔧

Some or all shocks listed are approved for road use; refer to the most recent certificate for current listings. Multiple style options are available, including full show-chrome or black covers, and either chrome or black springs and end caps. Made in the USA.

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 slightly and provide somewhat quicker steering; a shock slightly shorter than stock may provide somewhat slower steering.

Heavy duty applications are recommended for bikes operated at or 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 your wheel travel can be altered without causing clearance issues such as swingarm/axle to exhaust contact or chain/belt guard or tire contact.
