PROGRESSIVE SUSPENSION 412 Series Shocks — 279.40 mm (11.00"), rear, Black/Chrome – 71-86 Big Twin, 79-86 Touring, 82-86 FXR, 84 Police, 85-86 Softail

Designed specifically for Harley models, the 412 Series offers a simple, durable design that delivers a cost-effective upgrade to your motorcycle's suspension performance.

A five-position cam-style spring preload adjuster lets you easily dial in your ride.

Some or all shocks listed are approved for road use; refer to the most recent certificate for the current listing.

Multiple style options are available, including different cover and spring finishes to suit your bike.

All shocks are measured center-to-eyelet to center-to-eyelet. Before purchasing or attempting to install shocks that differ from OEM length, confirm wheel travel and clearance to avoid contact with swingarm, axle, exhaust, chain/belt guard, or tire.

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 can alter head angle and provide somewhat quicker steering; a slightly shorter shock can result in somewhat slower steering.

Heavy duty applications are recommended for bikes that are operated at or near the manufacturer's maximum load rating over 50% of the time.
