The Ohlins HD517 STX 46 American V-Twin rear shock is built for Harley-Davidson Softail fitments where controlled damping and ride stability matter. It uses a monotube design with a separated oil and gas layout to support consistent damping behaviour as conditions change. Tuning is straightforward, with external adjusters to match rider preference and load.

Ohlins | Made to race, perfected to ride

Developed from Ohlins performance suspension experience, this rear unit is intended to deliver predictable chassis control on the road. The STX architecture focuses on maintaining damping stability and clean feedback through the rear end.

Who this shock is for

  • Softail riders wanting improved damping control over the standard rear shock
  • Owners who change load (solo vs luggage) and want tunability
  • Riders who value consistent feel across varied road surfaces

Shock design & features

  • Rear monotube shock design
  • Separated oil and gas construction to reduce fade and support stable damping
  • STX 46 American V-Twin platform intended for Harley-Davidson Softail applications

Tuning controls

Before you install

  • Confirm the application list matches your exact Softail model and year
  • Inspect related mounting hardware and bushes during installation

Serviceability/lifecycle

Ohlins shocks are serviceable units designed to be maintained over time. Periodic servicing helps keep damping performance consistent and extends component life.

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.
