Frequently Asked Questions

Can I adjust the preload on the road?

Yes — the hose-mounted hydraulic preload adjustment lets you dial in preload for weight changes without tools, though a preload tool is included for more precise settings.

Does this shock come with installation instructions?

Yes. Professional installation is strongly recommended to ensure proper alignment, bleed procedures, and damping setup for your bike and riding style.

What's the difference between rebound damping and preload?

Preload sets ride height and sag; rebound damping controls how quickly the shock extends after compression. Both are adjustable on this shock.

Will this fit my 2017 or earlier Softail?

No — this shock is engineered specifically for 2018-2024 Softail Heritage models. Older Softails require a different part number.

Is a preload tool included?

Yes — Ohlins includes a preload adjustment tool in the box for fine-tuning sag and ride height.
