Progressive Suspension Series 412 without Covers Shock absorberRef : PRSU00041A / 13100486

Series 412 Shock Absorber without Covers by PROGRESSIVE SUSPENSION (manufacturer part no. 412-4077C): a shock absorber designed for Harley touring bikes, focused on touring and heavy use. Its simple and robust design provides a reliable upgrade to the suspension without frills, maintaining the typical chrome look that suits customs.

• Adjustment: 5-position cam preload for quick adaptation of the stance according to rider, passenger, or luggage.
• Construction: steel body, chrome finish, internal reservoir, and gas-charged damping for consistent performance over long distances.
• Duty: heavy duty — recommended for motorcycles frequently used near the manufacturer's maximum load (>50% of the time).
• Dimensions: extended length 330 mm (13") measured centre to centre of eyelet.
• Manufacturing: designed and assembled in the United States.

Before installation, check compatibility: some models may require modification or a spacer for the chain/belt guard (notably the XL '86-'15). A shock absorber longer or shorter than the original may slightly alter the rake angle and steering responsiveness. Ensure that the travel does not cause contact between the swingarm/exhaust or chain/protection. Some references are road approved — consult the most recent certificate for the updated list.

Suitable for Harley Touring and customs requiring robustness and simple adjustments to regain road handling, comfort, and load capacity on long journeys.
