PROGRESSIVE SUSPENSION 412 Series Shocks — 305 mm (12.00 in), rear, black or chrome – 73-86 Big Twin, 79-80, 84 Touring, 82-86 FXR, 84 Police, 85-86 Softail

Designed specifically for Harley models, the 412 Series Shocks deliver a simple, durable, cost-effective improvement to your motorcycle's suspension performance. 🏍️

A five-position cam-style spring-load preload adjuster lets you quickly and 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 either chrome or black springs and end caps.

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 head angle for somewhat quicker steering, while a slightly shorter shock may provide somewhat slower 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 that wheel travel can be altered without causing clearance issues such as swingarm/axle to exhaust contact, chain/belt guard contact, or tire contact. Made in the USA. 🇺🇸
