PROGRESSIVE SUSPENSION 412 Series Shocks — Extended length 292.00 mm (11.50 in) – 84-85 Big Twin, 80-06 Touring, 00-05 CVO, 82-94 FXR, 77-03 Sportster

Designed specifically for Harley models, the 412 Series offers a simple, durable upgrade that improves suspension performance and value. 🔧

The five-position cam-style spring preload adjuster lets you quickly dial in your ride, and multiple style options—full show chrome or black covers, chrome or black springs and end caps—help you match your bike's look.

All shocks are measured center-of-eyelet to center-of-eyelet; when installing on '86-'15 XL models it may be necessary to modify or space the chain/belt guard for proper clearance.

Before changing OEM length, confirm wheel travel and clearances to avoid swingarm/axle to exhaust contact, chain/belt guard interference, or tire contact. Heavy duty applications are recommended when operating near the manufacturer's maximum load rating more than 50% of the time.
