The Ohlins HD939 STX 36 twin rear shock is built for Harley-Davidson FLHRC-I fitment where control and consistency matter. It uses a gas-pressurised damping design to maintain stable behaviour as conditions change. Independent damping circuits give you practical adjustment range to match your load, tyres and road surface.

Ohlins | Made to race, perfected to ride

Developed from Ohlins performance suspension know-how, this rear twin-shock package focuses on predictable grip, clear feedback and chassis stability. The damping layout is intended to stay consistent over long rides and varied temperatures.

Who this shock is for

  • Harley-Davidson FLHRC-I riders wanting a more controlled rear end without losing ride quality
  • Riders who carry luggage or a passenger and want damping you can tune
  • Owners chasing improved stability through braking and cornering on real roads

Shock design & features

  • STX 36 twin-shock rear configuration
  • Gas-pressurised damping system
  • Separate compression and rebound damping circuits
  • Race-proven valving approach for improved traction and stability

Tuning controls

This unit provides external adjustment for compression damping and rebound damping. These controls let you balance support and comfort, and fine-tune how the rear settles under braking and drives out of corners.

Before you install

  • Confirm the application matches Harley-Davidson FLHRC-I and rear twin-shock mounting
  • Check spring and hardware condition during fitting, and set sag before making damping changes
  • If you are changing load or tyres, re-check your settings after the first ride

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.
