The Ohlins HD504 STX 46 Custom & Heritage rear shock is built for Harley-Davidson Softail models where classic styling needs to be matched with consistent damping control. It’s designed to improve composure over bumps and maintain stability without changing the character of the bike. External adjusters let you tailor the feel to your load, riding pace and road conditions.

Ohlins | Made to race, perfected to ride

Part of the STX 46 Custom & Heritage family, this unit combines Ohlins damping know-how with finishes intended to suit custom and heritage builds. It’s a rear mono shock application for select Softail models.

Who this shock is for

Suited to riders chasing better control and support on the road, especially when ride quality and chassis stability matter as much as appearance. It’s also a sensible choice if you regularly vary load with a passenger or luggage and want the suspension to keep up.

Shock design & features

This is a gas-pressurised monotube shock with the Ohlins STX architecture, aimed at keeping damping performance consistent through changing conditions. The design is intended to balance comfort with a more planted feel during braking, acceleration and cornering.

Tuning controls

  • Rebound damping adjustment to control how quickly the shock extends after a bump
  • Compression damping adjustment to influence support and impact absorption
  • Spring preload adjustment to set ride height and support for different loads

Before you install

Confirm fitment to your exact Softail model and check clearance around exhaust, guards and accessories. After installation, set sag with preload first, then use compression and rebound adjustments to refine comfort and control.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced and reconditioned to maintain performance over time. Periodic servicing helps preserve damping consistency and seal life, particularly on bikes used regularly or in harsher conditions.

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.
