The Ohlins HD218 STX 36 twin rear shocks are built for Harley-Davidson Dyna FXD models needing more controlled damping and a more composed chassis over real-world roads. This is a gas-pressurised twin-shock set-up designed to maintain consistent response as conditions change. Adjustment is focused on rebound damping and spring preload for practical tuning without complexity.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a clear engineering focus: stable damping control, predictable feedback, and repeatable tuning. On a Dyna, that translates to better support through corner entry and improved stability when load and grip vary.

Who this shock is for

Suited to riders who want a more controlled rear end on a Dyna FXD without moving away from a twin-shock layout. It’s a solid match for street use where consistency, traction feel, and ride control matter more than chasing extremes.

Shock design & features

This is a gas-pressurised design that helps reduce damping fade during longer rides and repeated heat cycles. The STX 36 twin-shock architecture is intended to deliver stable damping characteristics and good sensitivity across typical road inputs.

Tuning controls

  • Rebound damping adjustment to control how quickly the rear returns after compression, influencing stability and grip feel.
  • Spring preload adjustment to set ride height support for rider weight and load.

Before you install

  • Confirm fitment for Harley-Davidson Dyna FXD and ensure both shocks are installed as a matched pair.
  • Set preload for your typical rider/load first, then fine-tune rebound damping to suit your road conditions.
  • After installation, re-check fasteners and clearances through full suspension movement.

Serviceability/lifecycle

Like other Ohlins units, these shocks are designed to be maintained to keep damping performance consistent over time. Periodic servicing is recommended as operating hours and conditions accumulate.
