Function and area of application

The 412 Series shock absorbers are designed for heavy-duty use and are suitable for riders who require a robust suspension solution. The gas-filled damper method provides consistent damping that automatically adapts to different driving conditions. The progressive spring rate enables a graduated spring effect that responds smoothly to small bumps and offers higher spring force under larger loads.

The use of steel as a material ensures high resilience and longevity. The black surface provides a subtle look that blends well with the appearance of the Harley Davidson Dyna. It is mounted on the rear axle, with the reservoir positioned internally in order to maintain a compact design and not restrict freedom of movement.

Summary

The PROGRESSIVE SUSPENSION 412 Series shock absorbers offer a solid, low-maintenance solution for the rear suspension of the Harley Davidson Dyna. They combine automatic damper adjustment with a progressive spring action and are designed for demanding use. The pair of shock absorbers is made of durable steel and impresses with its compact design with an internal reservoir.
