The Ohlins HD220 STX 36 is a rear twin-shock unit designed for Harley-Davidson Dyna FXD models. Built around Ohlins road and race suspension know-how, it focuses on controlled damping and consistent feel over varied riding conditions. This is a gas-pressurised design intended to maintain damping stability during extended use.

Ohlins | Made to race, perfected to ride

Ohlins suspension is engineered to deliver clear chassis feedback and predictable control. The STX 36 twin-shock format suits Harley-Davidson applications where balanced rear support and damping quality are priorities.

Who this shock is for

Suited to riders who want improved rear-end control and a more planted feel from their Dyna FXD. It’s a fit for spirited road riding where stability under braking and confidence through corners matter.

Shock design & features

This is a gas-pressurised rear twin-shock setup designed to reduce fade and help keep damping consistent as temperatures rise. The STX 36 family is aimed at delivering stable traction and improved ride quality through well-controlled valving.

Tuning controls

This unit provides adjustable damping for both compression and rebound, allowing you to tailor shock response to your riding style and conditions. Independent circuits help separate support (compression) from recovery control (rebound).

Before you install

  • Confirm the application is correct for Harley-Davidson Dyna FXD and rear twin-shock fitment.
  • Set sag and check spring suitability as part of installation.
  • After installation, re-check fasteners and clearances through full suspension travel.
