Series 412 Shock Absorber without Covers – PROGRESSIVE SUSPENSION (Manufacturer's ref: 412-4063B). Specifically designed for Harley models, this Series 412 shock absorber set provides a robust and economical solution to replace your original suspensions. Discreet black finish, steel body with internal reservoir and gas-charged damping system: equipment designed to last and remain understated on a Roadster.

• Extended length: 292 mm (11.50"). Measurement from centre to centre of the eyelet.
• Adjustment: 5-position cam spring preload for quickly adjusting the seat hold according to load or passenger.
• Material: steel with compatible springs in black or chrome depending on variations.
• Usage: standard function, suitable for road use; Heavy Duty options recommended if you frequently ride near the manufacturer's maximum load.

Installation notice: on certain models (notably XL '86-'15), it may be necessary to modify or space the chain/belt guard to ensure clearance. A shock absorber slightly longer or shorter than the original may alter the rake angle and thus the responsiveness of the steering. Always check the travel and clearances (swingarm, exhaust, chain/guard, tyre) before installation.

Examples of applications: Harley-Davidson Sportster Forty-Eight and Superlow (2020 models listed). Product made in the USA. Please consult the most recent homologation certificate for accepted road references.
