The Ohlins HD778 STX 36 Blackline shock pair is designed for Harley-Davidson rear fitment where improved control and ride quality are priorities. Built around Ohlins STX architecture, it focuses on consistent damping performance with practical adjustability for real-world loads and road surfaces. The Blackline finish suits classic and custom builds without changing the bike’s character.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a clear engineering focus: stable damping behaviour, predictable response and long-term serviceability. This rear shock pair is tailored to Harley-Davidson touring and cruiser applications where comfort and composure matter as much as feel.

Who this shock is for

  • Harley-Davidson riders wanting a more controlled rear end for everyday road use.
  • Touring riders who regularly change load conditions (solo, passenger, luggage) and want adjustability.
  • Owners building a clean Blackline look while upgrading the suspension with a proven Ohlins unit.

Shock design & features

This is an Ohlins STX 36 Blackline rear shock pair for Harley-Davidson fitment. The design uses a separated oil/gas layout to help maintain damping consistency over longer rides. A Blackline finish is used to match darker or vintage-themed builds.

Tuning controls

Adjustability is provided for rebound damping, compression damping, and spring preload. This allows you to tune comfort and control, and to compensate for changes in rider weight or carried load.

Before you install

  • Confirm the application list matches your Harley-Davidson model (Electra Glide, Road Glide, Road King, Street Glide, Ultra Classic) and that you are fitting to the rear.
  • Set sag and preload for your typical riding load before fine-tuning damping.
  • If you are unsure about setup for your roads and riding style, plan to record baseline settings before making changes.

Serviceability/lifecycle

Ohlins shocks are designed to be maintained and serviced to keep performance consistent over time. Regular servicing helps preserve damping quality and internal condition, especially for high-use touring bikes.
