The Ohlins HD402 STX 36 Twin is a rear twin-shock setup built for Harley-Davidson fitments where damping control and consistency matter. It uses a monotube architecture with a gas-charged design to keep damping stable as conditions change. This unit is intended for riders who want a more controlled rear end and the ability to fine-tune feel.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the STX 36 Twin family focuses on predictable damping behaviour and a composed chassis response. It’s designed to deliver clear feedback without making the bike harsh.

Who this shock is for

Suited to riders looking to improve stability, support and grip from the rear of a Harley-Davidson with twin shocks. It’s a good match if you ride varied roads, carry load at times, or want a more settled feel under acceleration and braking.

Shock design & features

This is an emulsion-style monotube shock, with oil and gas working in the same main body to maintain consistent damping. The STX 36 Twin layout is designed to offer controlled movement and reliability in a compact twin-shock format.

Tuning controls

This model provides rebound damping adjustment, allowing you to dial in how quickly the rear returns after bumps and load changes. It’s intended for practical tuning to match rider preference, road conditions and spring choice.

Before you install

  • Confirm fitment for your specific Harley-Davidson model and any existing modifications.
  • Set sag and baseline rebound after installation so the shocks work in the correct part of their travel.
  • Inspect mounting hardware and bushes during installation and torque fasteners to the motorcycle manufacturer’s requirements.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to restore performance over time. Regular inspection and periodic servicing helps maintain damping consistency and keeps internal wear under control.
