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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
