Properties and area of application

The 412 Series shock absorbers are equipped with a gas-filled damper chamber that ensures consistent damping performance and improves responsiveness. The simple progressive spring rate provides a graduated spring action that adapts to different loads. This supports a stable driving style and increases comfort when driving with a heavy load or on uneven roads.

The automatic setting enables uncomplicated handling and adapts the damping to the respective driving conditions without manual intervention. The monotube design contributes to the longevity and reliability of the shock absorbers, while the internal reservoir protects the components and keeps the overall height low.

The black steel surface is robust and resistant to environmental influences. The extended length of 318 mm meets the requirements for rear wheel mounting on the Harley Davidson FLHRI.

Conclusion

The PROGRESSIVE SUSPENSION 412 Series shock absorbers offer a technically advanced solution for the rear suspension of the Harley Davidson FLHRI. They combine progressive spring characteristics with gas-filled damping and automatic adjustment to improve ride comfort and stability.
