If you have a built motor on stock suspension, you won't be able to put that extra power to the ground. Fortunately, Ohlins has you covered with their fully adjustable, high-performance rear shock for your Softail.
The STX Performance rear shock has been designed specifically for the M8 Softail platform and offers a large 46mm main piston, an internal gas reservoir hidden inside the main body of the shock, length adjustability, and a hydraulic preload adjuster. With adjustable damping, you can change the behavior of the shock to suit your taste.
The tool-free hydraulic preload knob allows you to make incremental adjustments completely separate from the mechanical preload on the spring, perfect for unexpected passengers!
Note: Fat Bob models come with a 13 1/2" Shock, all other models use 12 1/2" from the factory.
