PROGRESSIVE SUSPENSION 412 Series Shocks — 330 mm extended length, Black or chrome – 82-94 FXR, 77-95, 97-98, 00, 02-03 Sportster

412 Series shocks deliver a simple, durable upgrade to your motorcycle's suspension and are designed specifically for Harley models. 🏍️

A five-position cam-style spring preload adjuster makes it easy to dial in ride feel, while progressive spring rates help maintain control under varying loads.

All shocks are measured center-to-center eyelet and some or all listings are approved for road use; consult the most recent certificate for current approvals.

Before purchasing or attempting to install shocks that differ from the OEM length, confirm that wheel travel and clearances will not cause exhaust, chain/belt guard, or tire contact. Heavy duty applications are recommended for bikes operated near the manufacturer's maximum load frequently.

When fitting shocks to '86–'15 XL models, it may be necessary to modify or space the chain or belt guard for proper clearance. Slight length differences can alter head angle and steering response.
