The Ohlins HD616 is a rear STX 36 twin shock package built for Harley-Davidson Dyna FXD models where stable chassis control and consistent damping matter. It uses a gas-pressurised design to help maintain damping consistency during long or demanding rides. Independent damping circuits allow the feel to be tuned to rider preference and load.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, this twin shock setup is intended to improve traction, stability and control without compromising the practical requirements of a Harley-Davidson rear suspension layout.

Who this shock is for

Suited to Dyna FXD riders who want clearer feedback and better composure when braking hard, accelerating out of corners, or riding on variable road surfaces. It also suits riders who regularly adjust for different loads or riding conditions.

Shock design & features

  • Rear twin shock configuration for Harley-Davidson Dyna FXD fitment
  • Gas-pressurised damping to reduce fade and maintain consistency
  • Race-proven internal valving aimed at improving corner-exit traction and chassis stability

Tuning controls

Adjustable compression and rebound damping let you fine-tune support and control. This helps tailor ride quality and stability for different road conditions and riding styles.

Before you install

  • Confirm fitment for your exact Dyna FXD model and current rear hardware
  • Set sag and damping to suit rider weight and typical load before evaluating handling changes
  • Recheck fasteners and clearances after initial kilometres

Serviceability/lifecycle

Ohlins shocks are built to be serviced to maintain performance over time. Periodic oil and seal service helps keep damping consistent, particularly with frequent spirited riding or heavy use.
