The Ohlins HD159 STX 36 twin rear shock set is built for Harley-Davidson touring models that use a twin-shock rear end. It is designed to improve damping control and chassis stability while maintaining a compliant ride on real roads. This unit uses a gas-pressurised, separated oil/gas design to help keep damping consistent as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins suspension is engineered around stable damping behaviour and repeatable adjustment. The STX twin-shock platform focuses on controlled movement and predictable feedback for heavier motorcycles and varied load conditions.

Who this shock is for

  • Harley-Davidson touring riders wanting clearer chassis control and confidence through corners
  • Riders who regularly adjust their setup for different road surfaces or riding pace
  • Owners replacing worn standard shocks with a serviceable, tuneable unit

Shock design & features

  • STX 36 twin-shock rear configuration
  • Gas-pressurised damping with separated oil and gas to reduce aeration and maintain damping consistency
  • Valving aimed at stable traction and controlled body movement

Tuning controls

  • Rebound damping adjustment
  • Spring preload adjustment

Before you install

  • Confirm model compatibility and that your bike uses the correct twin rear shock mounting arrangement
  • Set spring preload to suit your typical load, then fine-tune rebound to control return movement without harshness
  • After installation, re-check fastener torque and clearances through full suspension travel

Serviceability/lifecycle

Ohlins shocks are designed to be maintained and re-valved by a suspension specialist. Periodic servicing helps keep damping performance consistent over time, especially on heavier touring motorcycles.
