The Ohlins HD402 STX 36 Twin is a rear twin-shock setup built for Harley-Davidson fitments where damping control and consistency matter. It uses a monotube architecture with a gas-charged design to keep damping stable as conditions change. This unit is intended for riders who want a more controlled rear end and the ability to fine-tune feel.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the STX 36 Twin family focuses on predictable damping behaviour and a composed chassis response. It’s designed to deliver clear feedback without making the bike harsh.

Who this shock is for

Suited to riders looking to improve stability, support and grip from the rear of a Harley-Davidson with twin shocks. It’s a good match if you ride varied roads, carry load at times, or want a more settled feel under acceleration and braking.

Shock design & features

This is an emulsion-style monotube shock, with oil and gas working in the same main body to maintain consistent damping. The STX 36 Twin layout is designed to offer controlled movement and reliability in a compact twin-shock format.

Tuning controls

This model provides rebound damping adjustment, allowing you to dial in how quickly the rear returns after bumps and load changes. It’s intended for practical tuning to match rider preference, road conditions and spring choice.

Before you install

  • Confirm fitment for your specific Harley-Davidson model and any existing modifications.
  • Set sag and baseline rebound after installation so the shocks work in the correct part of their travel.
  • Inspect mounting hardware and bushes during installation and torque fasteners to the motorcycle manufacturer’s requirements.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to restore performance over time. Regular inspection and periodic servicing helps maintain damping consistency and keeps internal wear under control.

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.
