Series 412 Shock Absorber without Covers – PROGRESSIVE SUSPENSION (Manufacturer's Ref: 412-4066B)

The Series 412 offers a robust and adjustable solution to replace your original shocks on several Harley models, particularly the Sportster. Made of steel with a black finish, this heavy-duty shock with an internal reservoir uses a gas-charged damping method to maintain consistent response under load. Its simple and reliable design makes it a practical choice for those looking to enhance suspension reliability without compromising aesthetics.

• Extended length: 292 mm (11.50") — measured centre to centre eyelet
• Spring preload adjustment: 5-position cam for easy adjustment
• Finish: black; material: steel
• Duty: heavy-duty — suitable for frequent load applications

Note: a shock absorber that is slightly longer or shorter than the original may alter the rake angle and handling characteristics. During installation (especially on XL models '86-'15), it may be necessary to space or modify the chain/belt guard to ensure clearance. Some or all of the listed shocks are road-legal; please check the most recent certificate for the updated list.

Application examples: Harley-Davidson Sportster (e.g. XL 1200 XS Forty‑Eight Special, XL 1200 X Forty‑Eight, XL 1200 T Superlow).
