Progressive Suspension - Series 412 Shock Absorber (manufacturer part no. 412-4067B)

Series 412 shock absorber designed for Harley roadster-type machines. Sleek black finish, steel body with internal reservoir and gas-charged damping system. Model delivered without covers — ideal for those seeking a robust and adjustable solution without unnecessary chrome.

• Adjustment: 5-position cam spring preload to adapt height and tension according to load and riding style.
• Duty: Heavy (reinforced use) — recommended for motorcycles frequently carrying loads close to or exceeding 50% of the manufacturer's capacity.
• Extended length: 279.40 mm (11.00") measured centre to centre.
• Material: steel; Colour: black.
• Damping method: gas-charged (internal reservoir).
• Made in the USA.

Installation notes: all shock absorbers are measured centre to centre. On some models (notably XL '86-'15), it may be necessary to adjust or space the chain/belt guard to ensure sufficient clearance. A shock absorber longer or shorter than the original may slightly alter the steering angle and responsiveness. Before installation, check the travel and clearances (swingarm, exhaust, belt/chain guard, tyre).

Common applications: Sportster Forty-Eight, Sportster Superlow and other XL 1200 models (check model/year compatibility before purchase).
