Product description

The 412 Series shock absorbers from PROGRESSIVE SUSPENSION are characterized by their robust steel construction. The monotube design enables precise damping, while the progressive spring rate ensures a graduated spring effect. This optimizes the handling of the Harley Davidson Sportster in the rear wheel area.

The automatic adjustment of the damping adapts to the driving conditions without the need for manual adjustment. This contributes to a more comfortable riding experience and supports the stability of the motorcycle under different loads.

The internal position of the reservoir ensures a compact design and protects the damper components from external influences. The black surface gives the shock absorbers an inconspicuous and functional appearance.

These shock absorbers are available as a pair and are suitable for standard use in the rear wheel area of ​​the Harley Davidson Sportster. They are part of the SUSPENSION GROUP-REAR and belong to the SHOCKS W/SPRINGS product type category.
