Ohlins 18-24 Harley Softail Heritage Classic STX 46 Shock 13in.

A well-proven monotube design, the Ohlins STX 46 shock absorber sets the standard for performance, quality, and durability. A major suspension upgrade for your Adventure, Street, or Naked Sport Bike. It features a large 46mm main piston and an internal gas reservoir within the main body of the shock. With adjustable damping, you can change the behavior of the shock to suit your taste and, with the provided preload tool, make adjustments for those weight changes to keep proper geometry.
