The Ohlins HD939 STX 36 twin rear shock is built for Harley-Davidson FLHRC-I fitment where control and consistency matter. It uses a gas-pressurised damping design to maintain stable behaviour as conditions change. Independent damping circuits give you practical adjustment range to match your load, tyres and road surface.

Ohlins | Made to race, perfected to ride

Developed from Ohlins performance suspension know-how, this rear twin-shock package focuses on predictable grip, clear feedback and chassis stability. The damping layout is intended to stay consistent over long rides and varied temperatures.

Who this shock is for

  • Harley-Davidson FLHRC-I riders wanting a more controlled rear end without losing ride quality
  • Riders who carry luggage or a passenger and want damping you can tune
  • Owners chasing improved stability through braking and cornering on real roads

Shock design & features

  • STX 36 twin-shock rear configuration
  • Gas-pressurised damping system
  • Separate compression and rebound damping circuits
  • Race-proven valving approach for improved traction and stability

Tuning controls

This unit provides external adjustment for compression damping and rebound damping. These controls let you balance support and comfort, and fine-tune how the rear settles under braking and drives out of corners.

Before you install

  • Confirm the application matches Harley-Davidson FLHRC-I and rear twin-shock mounting
  • Check spring and hardware condition during fitting, and set sag before making damping changes
  • If you are changing load or tyres, re-check your settings after the first ride
