The Ohlins HD538 STX 36 Twin shock package is a rear suspension solution for Harley-Davidson FL Touring models including Road King, Street Glide and Electra Glide. Built around Ohlins twin-shock architecture, it focuses on consistent damping control and a planted feel over varying road surfaces. This unit is suited to riders who want more composure and tunability from the rear of the bike.

Ohlins | Made to race, perfected to ride

Ohlins suspension is designed to provide controlled movement through the stroke, helping the tyre stay in contact with the road and keeping the chassis settled. The HD538 is part of the STX 36 Twin family, developed for Harley-Davidson touring applications where stability and comfort both matter.

Who this shock is for

Designed for Harley-Davidson FL Touring motorcycles using a rear twin-shock layout. It suits riders who carry varying loads, ride longer distances, or want more control and feel from the rear suspension without changing the bike’s character.

Shock design & features

This is an emulsion-type shock design, where oil and gas share the same working volume. The STX 36 Twin format supports predictable damping behaviour and a durable, serviceable construction intended for real-world road use on heavier touring platforms.

Tuning controls

This model provides rebound damping adjustment. Rebound control lets you manage how quickly the rear suspension extends after bumps and load changes, helping maintain stability and traction across different road conditions.

Before you install

Confirm fitment for your exact FL Touring model and any accessories that may affect clearance or load. After installation, set rider sag and then fine-tune rebound to match your typical riding conditions and payload.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain performance over time. Periodic oil and seal maintenance helps keep damping consistent, especially on bikes that see frequent kilometres or heavier loading.
