The Ohlins HD539 STX 36 Twin shock set is designed as a rear suspension upgrade for Harley-Davidson FL Touring models such as Road King, Street Glide and Electra Glide. It uses a gas-pressurised damping design to maintain consistent control as conditions change. Built around Ohlins experience in performance damping, it focuses on predictable chassis behaviour and clear rider feedback.

Ohlins | Made to race, perfected to ride

Ohlins suspension is built around stable damping characteristics and repeatable tuning. On touring platforms, that translates to more composed support through corners, braking zones and varying road surfaces.

Who this shock is for

Suited to FL Touring riders who want a more controlled rear end without compromising long-distance comfort. It’s also a practical choice if you carry luggage or a passenger and want more consistent suspension feel.

Shock design & features

This is a twin-shock rear setup in the STX 36 family with a gas-pressurised damper architecture. The gas pressure helps reduce fade and keeps damping response more consistent during extended riding.

Tuning controls

The damping circuits are independently adjustable for compression and rebound, allowing you to tailor support under load changes and manage how quickly the rear recovers after bumps. Spring preload adjustment is used to set ride height and balance for rider and payload.

Before you install

Confirm fitment for your exact Harley-Davidson FL Touring model and year, and set sag/preload after installation to suit your typical load. If you plan to change springing, match it to your riding weight and luggage/passenger use before finalising damping adjustments.

Serviceability/lifecycle

As with other Ohlins road units, periodic servicing helps maintain damping quality and seal life over time. Keeping the shocks clean and inspecting mounts and bushes during routine maintenance will help preserve performance.
