Product description

The 412 Series shock absorbers are equipped with a gas-filled damping method that ensures constant damping and improves handling. The automatic setting ensures easy handling without manual adjustments. The progressive spring rate allows for a graduated spring action that adapts to different loads, supporting comfort and control.

Made of steel and with a black surface, the shock absorbers are robust and resistant to environmental influences. The length of 279.40 mm (extended) meets the requirements for rear wheel mounting on Harley Davidson FX models. The internal reservoir contributes to the compact design and protects the damper components.
