Progressive Suspension – Series 412 Shock Absorber without Covers (Manufacturer's Ref: 412-4002B)

Designed for Harley customs and classic touring bikes, this Series 412 shock absorber offers a simple and robust upgrade for the rear suspension. Sleek black finish, steel body, and internal reservoir for a clean look. Gas-charged damping and 5-position cam preload adjustment to tailor the handling according to load and riding style.

• Extended Length: 330 mm (13.00") measured centre to centre of eyelet
• Material: steel, black finish
• Damping Method: gas
• Adjustment: 5-position preload (cam)
• Manufacturing: United States

Suitable for Vintage/Classic, Roadster, and Touring universes. Some models in the range are road-legal; please check the latest manufacturer certificate for the up-to-date list. Note: installation on certain Harleys (notably XL '86-'15) may require modification or addition of a spacer to the chain/belt guard to ensure clearance. A shock absorber that is slightly longer or shorter than the OEM may also alter the rake angle and handling characteristics.

Ideal for those seeking reliable damping and a subtly reworked look without covers, the Series 412 integrates naturally on Electra Glide and other FLT/FLHT/FLTR '84-'05 (standard) as well as on certain Heavy Duty variants recommended for high-load use.
