The Ohlins HD516 STX 46 Custom & Heritage rear shock absorber is built for Harley-Davidson Softail models where comfort, stability and consistent damping matter. It combines classic-looking finishes with modern internal design to sharpen control without losing the character of a cruiser. Adjustment range is provided so the suspension can be matched to rider load and typical road conditions.

Ohlins | Made to race, perfected to ride

Ohlins suspension focuses on controlled damping and repeatable setup, giving riders a clear path to improving ride quality through correct adjustment rather than guesswork. The HD516 is part of the STX 46 Custom & Heritage family and is designed to suit custom and heritage-focused Harley-Davidson applications.

Who this shock is for

  • Softail riders wanting a more settled ride over rough roads and varying surfaces
  • Owners carrying a passenger or luggage who need to reset preload and damping for the extra load
  • Custom and heritage builds where appearance matters as much as function

Shock design & features

  • Rear mono shock design for Harley-Davidson Softail fitment
  • STX 46 Custom & Heritage architecture aimed at improved damping control and ride comfort
  • Oil and gas separated design for more consistent damping during use

Tuning controls

  • Rebound damping adjustment to control how quickly the shock extends after a bump
  • Compression damping adjustment to manage how the shock absorbs impacts and weight transfer
  • Spring preload adjustment to set ride height and support for rider/passenger load

Before you install

  • Confirm model compatibility for Harley-Davidson Softail Heritage Classic and Softail Low Rider ST
  • This unit replaces HD 505 (as noted for this part)
  • After installation, set sag and then fine-tune rebound and compression to suit your typical riding

Serviceability/lifecycle

Ohlins shocks are designed to be serviced, allowing oil and wear components to be refreshed to keep damping consistent over time. Routine servicing is recommended as part of long-term ownership, particularly if the bike is used regularly or loaded.

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.
