The Ohlins HD502 STX 46 Custom & Heritage rear shock absorber is built for Harley-Davidson Softail models that need improved control without losing classic styling. It uses an oil/gas separated design to maintain consistent damping over varying road conditions. With external adjustments for rebound, compression and spring preload, it can be tuned to suit rider preference and load.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on predictable damping behaviour and clear adjustment response. The Custom & Heritage range is intended to complement cruiser and custom builds while delivering modern suspension performance.

Who this shock is for

Suited to riders of Harley-Davidson Softail Deluxe, Softail Low Rider, Softail Low Rider S, Softail Slim and Softail models who want a more controlled ride and the ability to tailor suspension feel. It also suits custom builds where appearance matters alongside function.

Shock design & features

This is an STX 46 Custom & Heritage rear shock with a separated oil/gas layout. The architecture is designed to support stable damping performance and improved ride control compared with basic, non-adjustable units, while keeping finishes appropriate for heritage-style motorcycles.

Tuning controls

  • Rebound damping adjustment to manage how quickly the shock extends after a bump.
  • Compression damping adjustment to control resistance as the shock compresses under load.
  • Spring preload adjustment to set ride height and support for rider weight, accessories and luggage.

Before you install

Confirm fitment for your exact Softail variant and any modified chassis or exhaust components. This model is noted as replaced by HD 504, which may matter for availability and parts support planning.

Serviceability/lifecycle

Like other Ohlins units, the HD502 is intended to be maintained rather than treated as disposable. Periodic servicing helps keep damping performance consistent over the long term and supports reliability for regular road use.

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.
